Dhaulagiri Circuit Trek – 25 Days

The journey to the Dhaulagiri trailhead begins with the 6-7 hour drive from Kathmandu to Pokhara on the Prithvi Highway – Nepal’s main east-west artery through the middle hill country. The road follows the Trishuli and then the Marsyangdi River valleys westward before arriving at the lake city of Pokhara, the gateway to the Annapurna and Dhaulagiri trekking regions.

Pokhara is Nepal’s second largest city and its finest mountain town – spread along the shore of Phewa Lake with the full Annapurna massif and the Fishtail of Machhapuchhre rising above the northern horizon. The views from Pokhara of the Annapurna range – particularly at sunrise and sunset when the peaks glow pink and orange above the lake – are among the finest accessible from any Nepal city. Use the afternoon in Pokhara to make any final gear checks, relax at the lakeside, and confirm the logistics of the jeep departure to Darbang the following morning. Overnight in Pokhara.

An early morning departure from Pokhara for the jeep drive eastward and northward through the Myagdi district to the trailhead at Darbang (1,180m). The road follows the Kali Gandaki River eastward to Beni – the large market town at the confluence of the Kali Gandaki and Myagdi rivers – and then continues north up the Myagdi Khola valley to Darbang. The drive takes 3-4 hours and passes through the increasingly hilly and forested landscape of the western Nepal middle hills.

From Darbang the trek begins immediately – heading north up the Myagdi Khola valley on a well-defined trail through fields of corn and millet, past traditional Magar village houses, and along a river that runs clear and fast through a gorge of beautiful subtropical forest. The trail crosses several suspension bridges and passes through the small settlements of the lower valley before climbing to Dharapani (1,890m) – the first overnight stop and the point from which the full sweep of the Dhaulagiri massif appears above the valley wall for the first time.

The view from Dharapani on a clear afternoon is extraordinary – Gurja Himal (7,193m) and Putha Hiunchuli (7,246m) visible to the northwest, and the distant white profiles of the Dhaulagiri massif showing above the northern ridgeline in a first glimpse of the mountain world ahead. The Magar community of Dharapani – warm, direct, and entirely comfortable with their remote valley position – provides a fine introduction to the cultural world of the lower circuit. Drive time: 3-4 hours. Walking time: 3-4 hours.

From Dharapani the trail continues northward up the Myagdi Khola valley – the river crossing from bank to bank on suspension bridges, the trail following the valley floor and then climbing hillside sections above the water, passing through a sequence of Magar villages whose traditional stone and timber architecture, carved wooden facades, and warm community character define the cultural world of the lower Dhaulagiri circuit.

The trail passes through Sibang and then climbs to the village of Muri (2,150m) – a pleasant Magar settlement on a terraced hillside above the river with excellent views of the Dhaulagiri range beginning to build in the northern skyline. The forest sections between the villages of the lower circuit are rich in birdlife and in spring carry the flowering rhododendron display that characterizes the mid-altitude forests of western Nepal. The pace of life in the Magar villages of the lower valley – agricultural, unhurried, and largely outside the influence of mass trekking tourism – provides exactly the kind of cultural encounter that genuinely off-beaten-path trekking is supposed to deliver. Walking time: 5-6 hours.

The trail above Muri enters increasingly wild territory as the valley narrows and the forest thickens on both sides of the Myagdi Khola. The route climbs steadily through mixed subtropical and temperate forest – bamboo and oak in the lower sections giving way to rhododendron and the first conifer stands as altitude increases.

The trail passes through Gatti Khola and then climbs to the village of Naura (2,500m) or the adjacent settlement of Lipshe – a remote and beautiful location in the upper-middle Myagdi valley where the Dhaulagiri massif comes into increasingly detailed view to the north and where the character of the trail shifts from the inhabited lower valley to the wilder, less-populated upper approach.

The Magar communities of these mid-valley settlements maintain a traditional agricultural life organized around buckwheat, potato, and barley cultivation at this altitude – the same crops and the same farming practices that have sustained these communities for generations in the shadow of the great mountain to the north. The prayer flags and mani walls that begin appearing in the mid-valley settlements signal the Buddhist cultural influence that increases as the approach to the high mountain world continues. Walking time: 5-6 hours.

A day of descent before the long sustained climb of the upper circuit. From Naura the trail descends steeply to the river and follows the Myagdi Khola northward through increasingly dramatic gorge terrain to Bagar (1,780m) – a small settlement at the edge of the alpine zone that marks the practical end of the teahouse trail and the beginning of the full wilderness camping section above.

The descent to Bagar follows the river through a beautiful section of mixed forest – the gorge narrowing on both sides with vertical cliffs above the water in places and the river roaring through the narrow canyon below the trail. The landscape here already carries the character of the high mountain world approaching – the peaks of the Dhaulagiri massif visible in the north, the forest becoming more conifer-dominated with altitude, and the quietness of a valley that very few visitors enter.

Bagar is the last settlement with basic teahouse facilities before the circuit enters the true wilderness above. Ensure all camping equipment and food supplies are confirmed and properly organized this evening. The next section from Bagar to Marpha is entirely camping – no teahouses, no shops, no infrastructure of any kind. Everything the circuit needs is carried by the team from this point. Walking time: 5-6 hours.

The wilderness section of the Dhaulagiri Circuit begins. From Bagar the trail enters the upper Myagdi Khola valley on a trail that becomes progressively less defined and more dependent on your guide’s specific knowledge of the route. The river crossing pattern continues – suspension bridges giving way to log bridges and then to ford crossings as the valley narrows above the last settlement.

The trail passes through increasingly dramatic gorge terrain – the valley walls rising steeply on both sides, the vegetation changing from mixed forest to the denser, more primeval character of the upper gorge, and the first sections of challenging trail appearing on the route. Landslide-prone slopes require careful navigation in several sections.

Dobang (2,520m) is a seasonal settlement used by high-altitude herders – a flat area near the river where the camping crew sets up camp for the first full wilderness night of the circuit. The forest around Dobang is beautiful and the sounds of the upper Myagdi Khola running through the gorge below provide a constant and entirely pleasant background. The mountain views have opened significantly from this location – Dhaulagiri IV and the first glimpses of the great massif above the valley walls. Walking time: 5-6 hours.

From Dobang the trail continues its northward ascent through the upper gorge, gaining significant altitude through a sequence of sustained climbs and river crossings. The forest character above Dobang shifts completely from the deciduous species of the lower valley to the conifer-dominated forest of the high approach – tall stands of Himalayan pine, fir, and juniper providing shelter from the increasing cold and wind of the upper valley.

The trail passes through the camping area of Sallaghari (3,110m) – sometimes called Chhonbardan – where a flat area near the river provides the camping ground for the night. The views from Sallaghari begin to deliver the Dhaulagiri massif in earnest – the northeast face of Dhaulagiri I visible above the valley walls in the north, the scale of the mountain growing with every meter gained on the approach.

This section of the trail requires some of the most careful river navigation of the entire circuit – multiple crossings of the Chhonbardan Khola on whatever log bridges and stepping stones the current season has left intact. Your guide knows the current crossing conditions and leads the group through each section with appropriate care. Walking time: 5-6 hours.

The approach to the first base camp of the circuit – a sustained climbing day that takes the trail out of the closed gorge world of the lower approach and into the open, glacially-influenced landscape of the Chhonbardan Glacier basin. From Sallaghari the trail climbs steeply through the thinning forest, following the Chhonbardan Khola northward through progressively more open terrain as the tree line approaches.

Above the tree line the trail enters the lateral moraine of the Chhonbardan Glacier – the character of the landscape changing immediately and dramatically from forested gorge to the raw, rocky, open world of glacial terrain. The Chhonbardan Glacier is one of the largest glaciers accessible from any standard Nepal trekking route and its scale – the ice visible to the east as the trail climbs the lateral moraine – is genuinely impressive.

Italian Base Camp (3,660m) sits on a broad moraine shelf with direct and close-up views of Dhaulagiri II (7,751m), Dhaulagiri III (7,715m), Dhaulagiri IV (7,661m), and the extraordinary profile of Tukuche Peak (6,920m) rising to the east. The camp was used by Italian mountaineering expeditions to the Dhaulagiri massif in the post-war era of Himalayan exploration and its name reflects that history. The views from the camp in the late afternoon – the Dhaulagiri peaks catching the last light above the glacier – are among the most spectacular of the entire circuit. Walking time: 5-6 hours.

A full rest and acclimatization day at Italian Base Camp – critical before the significant altitude gains of the days above and deeply rewarding as an opportunity to explore the extraordinary glacial landscape surrounding the camp.

The morning acclimatization hike climbs above the camp on the lateral moraine – gaining altitude toward approximately 4,000-4,200m before returning. The views from the upper moraine directly above Italian Base Camp are the finest panoramic views of the Dhaulagiri massif available from the lower circuit – the full sweep of Dhaulagiri I, II, III, IV, and Tukuche Peak visible simultaneously across the glacier basin.

An extraordinary waterfall descends the left valley wall above the camp – a high cascade visible from the camp area that is one of the natural highlights of the Italian Base Camp location. Early morning is the finest time to observe it – the combination of the waterfall, the glacier, and the Dhaulagiri peaks in the morning light makes the upper camp area one of the finest natural settings accessible on the circuit approach.

In the afternoon, explore the camp surroundings – walk the upper moraine, examine the glacier closely where it meets the moraine wall, and absorb the scale of the glacial basin around you. The glacier camp above is visible from here on a clear day – a preview of tomorrow’s destination. Rest well. The altitude gains of the next several days are significant. Acclimatization hike time: 3-4 hours return.

From Italian Base Camp the trail enters the glacier world fully. The route continues up the lateral moraine of the Chhonbardan Glacier, gaining over 500m of altitude through terrain that becomes increasingly challenging as the moraine narrows and the glacier ice appears more prominently on both sides.

The trail from Italian to Japanese Camp is one of the most technically involved sections of the lower circuit – not requiring technical equipment but demanding careful navigation through the boulder-strewn moraine, occasional short sections on the glacier ice itself, and the particular alertness required when moving through glacial terrain where the ground is uneven, unstable in places, and physically demanding throughout.

Japanese Camp (4,210m) sits on a moraine shelf with views back down the glacier basin to the Italian Base Camp and beyond, and forward toward the ice wall of the upper glacier approach and the Dhaulagiri northeast face rising above it. At over 4,200m the altitude is seriously felt – the air noticeably thinner, the physical effort of the day more demanding per hour than any previous day on the circuit. Eat well, drink water, and rest. Tomorrow is the approach to Dhaulagiri Base Camp. Walking time: 4-5 hours.

The approach to the most significant single campsite of the entire 25-day circuit. From Japanese Camp the trail continues upward through the moraine and then moves onto the glacier itself for the final approach to the base camp area – a section requiring crampons in icy conditions and the careful navigation of a crevassed glacial surface.

The upper glacier approach above Japanese Camp is where the full scale and the full drama of the Dhaulagiri massif becomes completely and overwhelmingly apparent. The northeast face of Dhaulagiri I (8,167m) rises directly above the base camp site in a sweep of ice, rock, and seracs that constitutes one of the most technically imposing mountain faces in the entire Himalayan range. The other Dhaulagiri summits – II, III, IV, V – are visible in various directions around the basin, and Tukuche Peak (6,920m) provides a spectacular complementary profile to the east.

Dhaulagiri Base Camp (4,750m) is the staging point for all expeditions attempting Dhaulagiri I via the northeast ridge – the standard route first used by the Swiss-Austrian expedition that made the first ascent on 13 May 1960. Standing at the camp and looking up at the northeast face from which the first ascenders descended after the summit – Peter Diener, Ernst Forrer, Albin Schelbert, Nyima Dorje, and Nawang Dorje on summit day – gives the location a specific historical resonance that adds meaning to the already extraordinary physical experience. Walking time: 4-5 hours.

A mandatory full acclimatization day at Dhaulagiri Base Camp before the French Pass crossing. This day is not optional – the jump from 4,750m base camp to 5,360m at French Pass with a camping night at 5,100m in the Hidden Valley requires the body to be fully adapted to the base camp altitude before the attempt.

The standard acclimatization hike climbs the hillside directly above the base camp to approximately 5,000-5,100m – gaining altitude and providing a preview of the approach terrain toward the French Pass. The views from the high point above the base camp are among the finest of the entire circuit – the full Dhaulagiri massif visible from close range, the Tukuche Valley visible to the north, and on clear days the distant white profiles of the Annapurna massif visible to the southeast.

Alternatively, a shorter acclimatization option explores the Tukuche Valley side of the basin – walking toward the north side of the camp area and absorbing the extraordinary panoramic views of the northern face of Dhaulagiri and the trans-Himalayan landscape visible toward the Mustang plateau in the distance.

Your guide takes pulse oximeter readings throughout the day and assesses each team member’s altitude readiness individually. Any trekker showing serious altitude symptoms at this stage requires descent and the guide’s assessment is final. The French Pass crossing day is the most physically demanding day of the entire circuit and approaching it without proper acclimatization is the primary safety risk of the entire trek. Rest. Eat. Drink water. Sleep as well as the altitude allows. Acclimatization hike time: 3-4 hours.

The approach toward the French Pass. From the base camp the trail heads toward the upper glacier and the approach ramp to the pass – a day of sustained climbing on glacier terrain that requires crampons, ice axes, and careful rope management on the steeper sections.

The route follows the Chhonbardan Glacier northward on its upper section – crossing the crevasse fields with your guide leading through the safest route between the cracks, climbing the lateral moraine ridges that frame the glacier, and eventually reaching the high camp area at Glacier Camp (4,950m) – the final camp before the French Pass crossing.

Glacier Camp is one of the most dramatically positioned campsites of the entire circuit – at nearly 5,000m, surrounded on three sides by the ice walls of the upper Chhonbardan Glacier basin, with the French Pass visible above to the north and the Dhaulagiri northeast face dominating the southern skyline. The ice towers of the glacier approach catch the afternoon light and the evening alpenglow on Dhaulagiri’s upper ridges from this elevation is one of the finest single visual experiences of the entire trek. Walking time: 4-5 hours.

A rest and exploration day at the high glacier camp – both a physiological necessity at nearly 5,000m before the demanding French Pass crossing and an extraordinary opportunity to experience life on an active Himalayan glacier.

The morning is spent exploring the glacier terrain around the camp – walking on the ice with crampons, examining the crevasses at safe distances, observing the ice formations and glacial features that the upper Chhonbardan presents at this elevation. Your guide provides a practical briefing on glacier safety that directly prepares the team for the crossing conditions above the camp.

The afternoon at Glacier Camp is one of the finest rest-day experiences on any Nepal trekking circuit – lying in the tent listening to the sounds of the glacier (the deep creaks and occasional sharp reports of ice movement), watching the light change on Dhaulagiri above, and experiencing the particular quality of complete isolation at 5,000m that the Dhaulagiri Circuit specializes in delivering. This is a place almost no one comes to. That fact settles in completely in the quietness of the afternoon. Exploration time: 3-4 hours.

The defining day of the entire 25-day circuit. Everything that has come before – the long approach through the Myagdi Khola valley, the camps at Italian Base Camp and Dhaulagiri Base Camp, the acclimatization days, the glacier crossing days – has been preparation for this.

The alarm sounds at 4:00 AM or earlier. In the complete darkness of the high glacier camp, the team rises, eats hot food in the cook tent, layers up completely – every available insulation layer, crampons fitted, ice axes distributed, headlamps on – and begins the approach to the French Pass (5,360m) in the pre-dawn cold.

The ascent from Glacier Camp to the French Pass gains over 400m on the upper Chhonbardan Glacier and the steep final approach to the col. The glacier in the early morning is firm and consolidated – the ideal condition for crampon travel. Your guide leads through the most direct and safest line, fixing ropes on the steepest sections. The pace above 5,000m is deliberately slow – one breath, one step, every movement controlled and conscious.

At the French Pass (5,360m) the panorama opens in a complete and overwhelming arc. The full Dhaulagiri massif – all five major summits visible from the southern aspect – fills the sky behind you. Ahead, the Hidden Valley drops into its extraordinary enclosed basin below. Tukuche Peak (6,920m), Dhampus Peak (6,012m), Mukut Himal (6,328m), Tashi Kang, Sita Chuchura (6,611m) form the surrounding horizon. The Annapurna massif and Nilgiri (7,061m) are visible in the distance to the south. On the very finest autumn days, Manaslu (8,163m) and Everest (8,848m) are visible as distant profiles above the southern horizon.

The descent from the French Pass into the Hidden Valley (5,100m) drops steeply from the col on the north side – rocky scree giving way to the flat, arid, completely enclosed basin of the Hidden Valley. The descent requires continued crampon technique and careful footing on the loose upper section before the terrain opens into the extraordinary floor of the valley.

The Hidden Valley deserves its name completely. It is enclosed on all sides by peaks above 6,000m. It receives no regular visitors. It has no permanent habitation. It sits at over 5,000m in a complete silence that is unlike anything accessible on a standard Nepal trekking route. Camping here overnight – under the stars of a high Himalayan sky with the surrounding peaks lit by moon or starlight – is one of the genuinely extraordinary experiences of the entire circuit. Walking time: 7-8 hours.

A full rest and exploration day in the Hidden Valley – critical acclimatization before the Dhampus Pass crossing and one of the most unique and most genuinely remote single-day experiences available on any Nepal trekking circuit.

The morning exploration climbs the northwestern ridge above the valley floor – a 45-minute ascent to a natural viewpoint from which the entire Hidden Valley is visible in its bowl-shaped completeness, framed by the peaks above on all sides. From this ridge on a clear morning, the panorama encompasses Dhaulagiri, Nilgiri, Annapurna, and the vast trans-Himalayan landscape of the Mustang plateau to the north – one of the widest and most complete Himalayan panoramas accessible from any standard Nepal trekking viewpoint.

The Hidden Valley also provides access to the base of Dhampus Peak (6,012m) – a trekking peak whose technical demands place it above the standard circuit but whose lower approach ridges provide extraordinary close-range viewing of the peak that dominates the western wall of the Hidden Valley. For trekkers with the appropriate equipment and prior mountaineering experience, the Dhampus Peak climbing permit can be arranged separately for an attempt from the Hidden Valley camp.

The afternoon is entirely free – rest, photograph, write, explore the valley floor, examine the extraordinary arid landscape of the high basin. At 5,100m in a completely enclosed and completely remote Himalayan valley, the quality of experience is unlike anything available at this altitude on any other standard Nepal circuit. Exploration time: 3-4 hours in the morning.

The second high pass of the circuit and the final sustained technical challenge before the long descent to the Kali Gandaki valley. From the Hidden Valley the trail climbs westward toward the Dhampus Pass (5,244m) – gaining altitude steadily through the arid high-basin terrain, crossing the rim of the Hidden Valley, and ascending to the col on the western wall.

The Dhampus Pass crossing is technically less demanding than the French Pass – the approach is on rocky terrain rather than glaciated ice and crampons may not be required depending on conditions. The col itself, at 5,244m, delivers a panorama of the Kali Gandaki world ahead – Nilgiri North (7,061m) rising dramatically above the valley, the vast plains of the Mustang plateau visible to the north, the Kali Gandaki gorge visible below, and the entire Annapurna massif spread across the southeastern horizon.

The descent from the Dhampus Pass is long and sustained – dropping over 1,500m from the col to the overnight camp at Yak Kharka (3,680m) through a sequence of descending terrain zones from high alpine rock to open pasture to the first sub-alpine scrubland of the upper Kali Gandaki approach. The yak herding area of Yak Kharka – the name means simply “yak pasture” – provides the final wilderness camp of the circuit, with the extraordinary contrast of the open, inhabited, agricultural world of the Kali Gandaki visible in the valley below. Walking time: 7-8 hours.

The final trekking day of the circuit and the most dramatically satisfying descent of the entire journey. From Yak Kharka the trail drops continuously and decisively toward the Kali Gandaki valley – the legendary river gorge that is regarded as the world’s deepest by some measurements, cutting between the massifs of Dhaulagiri and Annapurna in a gorge that drops from the Tibetan plateau to the lowlands of Nepal within a horizontal distance of barely 40 kilometers.

The descent passes through the tree line – the first trees since the Italian Base Camp approach far below on the east side of the circuit – and then through increasingly lush alpine pasture before arriving at the Kali Gandaki valley floor. The character of the Kali Gandaki is immediately distinctive – the wide, graveled river bed, the distinctive strong afternoon winds howling up the valley from the south, the red sandstone cliff formations of the Mustang geological province, and the flat-roofed whitewashed architecture of the Mustang-influenced villages.

Marpha (2,670m) is the arrival point of the circuit and one of the most celebrated villages in the Annapurna / Mustang trekking corridor. Famous for its apple orchards – the finest at this altitude in Nepal – and for the locally produced apple brandy that has made the village known throughout the trekking world, Marpha greets every trekker arriving from the Dhampus Pass descent with the specific warmth of the first proper, well-stocked teahouse after days in the wilderness. The warmth, the food, the company of other trekkers on the Annapurna Circuit arriving from Jomsom, and the apple brandy of Marpha are all appreciated more completely after the demands of the Dhaulagiri Circuit than they could be under any other circumstances. Walking time: 5-6 hours.

A full rest day in Marpha – one of the most genuinely earned rest days of any Nepal trekking itinerary. The body after the French Pass, the Hidden Valley, and the Dhampus Pass needs a full day of lower-altitude recovery, and Marpha at 2,670m provides the ideal environment for that recovery.

Marpha is a genuinely beautiful village – the traditional flat-roofed stone houses of the Mustang architectural style, the whitewashed lanes, the apple and apricot orchards surrounding the settlement, the small Marpha Monastery at the edge of the village, and the extraordinary surrounding landscape of red sandstone cliffs, the Kali Gandaki river bed, and the peaks of Nilgiri and Dhaulagiri visible above the valley walls in opposite directions simultaneously.

Spend the day eating well – the Marpha teahouses offer some of the finest food available anywhere on the Annapurna Circuit, including the famous apple pie and apple brandy that have become part of the village’s international trekking identity. Walk through the apple orchards. Visit the monastery. Sit by the river. Let the extraordinary experience of the circuit settle into the kind of memory that genuinely demanding journeys create.

A short walk of 1-2 hours from Marpha to Jomsom (2,740m) – the district headquarters of Mustang and the location of the airstrip that will carry you back to Pokhara and then Kathmandu. The walk from Marpha to Jomsom follows the Kali Gandaki valley southward through the characteristic strong afternoon winds of the Mustang corridor – the same wind that has howled through this valley for millennia and that makes the Jomsom area one of the windiest inhabited places in Nepal.

The 25-minute flight from Jomsom to Pokhara crosses the southern wall of the Annapurna massif in one of the finest short mountain flights available in Nepal – the full Annapurna range visible at close range from the aircraft window on a clear morning, with Dhaulagiri visible to the west providing a final aerial view of the mountain you have spent two weeks circumnavigating. Flights from Jomsom depart early morning before the valley winds strengthen and weather delays are always possible – patience and flexibility are required. Walking time to Jomsom: 1-2 hours. Flight time: 25 minutes.

A full rest day in Pokhara – Nepal’s finest mountain city and the perfect place to recover after the Dhaulagiri Circuit. The lakeside setting of Phewa Lake with the Annapurna massif above the northern horizon, the excellent restaurants and cafes of the tourist area, the massage and spa options, and the general warmth and comfort of a well-developed mountain resort city provide everything needed for a proper post-circuit recovery day.

Use the day however feels right – walk along the lake, take a boat out on Phewa Lake for a view of the Fishtail Mountain’s reflection in the water, eat well at one of Pokhara’s finest restaurants, and begin the pleasant process of letting the extraordinary experience of the Dhaulagiri Circuit settle into memory.

The return to Kathmandu from Pokhara – either by the 6-7 hour tourist bus journey on the Prithvi Highway or by the 25-minute domestic flight over the hills between the two cities. The bus journey is scenic and comfortable; the flight is spectacular on a clear morning with the Annapurna and Dhaulagiri ranges visible from the aircraft window. Either option brings you back to the capital city in time for the afternoon or evening. Overnight in Kathmandu.

A practical buffer day in the itinerary for potential Jomsom flight delays – the Kali Gandaki valley winds are among the most reliably disruptive weather factors on Nepal domestic aviation and delays of one or two days are entirely normal. This buffer day ensures that any such delay does not affect your international departure.

If the journey returned on schedule, the buffer day is a free day in Kathmandu. Visit any cultural sites not yet seen – Pashupatinath Temple, Boudhanath Stupa, Swayambhunath, Patan Durbar Square – or simply rest, shop in Thamel, and let the Dhaulagiri Circuit settle into the long-term memory where the finest journeys always eventually live.

Your 25-day Dhaulagiri Circuit Trek comes to a close. Our team transfers you to Tribhuvan International Airport. You leave Nepal having completed a genuine wilderness circuit around the world’s seventh highest mountain – one that sees only a few hundred trekkers per year and that requires every quality of preparation, fitness, and mental resilience that long wilderness trekking demands in its most uncompromising form.
