Stunning Chomolhari Trek 14 Days

• Stand at Jangothang, the legendary Jomolhari Base Camp, face-to-face with the east wall of Mt. Chomolhari (7,315 m), one of the most photographed mountain views in the eastern Himalaya.
• Cross two of Bhutan’s highest trekking passes, Nyele La (4,890m) and Yeli La (4,930m), both strung with prayer flags and framed by 7,000m peaks.
• Spend a full acclimatization day at Jangothang with the option to hike up to the glacial Tshophu Lakes, where blue sheep graze the surrounding ridgelines.
• Trek through Jigme Dorji National Park, home to snow leopards, takins, Himalayan griffons, and some of the last intact yak-herding communities in the Himalaya.
• Pass the ruins of Lingshi Dzong and Barshong Dzong, remote fortresses that once guarded Bhutan’s northern frontier.
• Walk through the shifting landscape of the trek, from subtropical Paro Valley farmland to alpine tundra above 4,000m and back down into Thimphu’s bamboo forest.
• Hike to Taktsang Monastery, the cliffside Tiger’s Nest, as part of your Paro sightseeing before or after the trek.
• Round out the journey with valley time in Thimphu and Punakha, visiting Punakha Dzong, Dochula Pass, and Chimi Lhakhang.

The Chomolhari Trek, also known as the Jomolhari Trek, is Bhutan’s answer to Everest Base Camp: a high-altitude classic that trades crowded trails for near-total solitude. Bhutan’s strict tourism policy keeps visitor numbers low across the entire country, and nowhere is that more apparent than on this trail, where you are far more likely to cross paths with a yak herder than another trekking group.

This 14-day itinerary gives the classic Jomolhari route the time it deserves. Rather than rushing straight out and back, it follows the longer traverse from Paro to Thimphu, crossing both Nyele La and Yeli La passes and passing through the remote settlements of Lingshi, Shodu, and Barshong before descending to the capital. A full acclimatization day is built in at Jangothang, and the trip closes with proper time in Thimphu and Punakha rather than a rushed drive straight to the airport.

Along the way, the trail moves through some of the widest ecological range found on any Himalayan trek, from warm pine and oak forest in the lower Paro Valley to bare alpine tundra above the tree line, all within a protected national park believed to shelter Bhutan’s elusive snow leopard population. Add to that the ever-present backdrop of Mt. Chomolhari, a peak considered sacred and off-limits to climbers, and this trek offers something rare: genuine Himalayan wilderness paired with living Bhutanese culture at either end.

What Makes the Chomolhari Trek Special:

• Full traverse route from Paro to Thimphu, rather than the shorter out-and-back loop
• Two high mountain passes above 4,800m, both with spectacular Himalayan panoramas
• A dedicated acclimatization day at Jomolhari Base Camp with an optional lake hike
• Trekking entirely within Jigme Dorji National Park, one of the Himalaya’s last snow leopard habitats
• Full support crew with pack animals, camping equipment, and cook staff
• Bookended by cultural time in Paro, Thimphu, and Punakha, including the Tiger’s Nest hike
• Low trekker density thanks to Bhutan’s sustainable tourism model

The Stunning Chomolhari Trek is graded as challenging. It is a genuine high-altitude trek crossing two passes near 4,900m, and it demands solid trekking fitness and prior camping-trek experience.

Elevation Profile

• Lowest point: Paro at 2,250m
• Highest point: Yeli La Pass at 4,930m
• Nine consecutive trekking days above 2,800m, four of them above 4,000m

Daily Walking Expectations

• Most trekking days run 5 to 8 hours, with two long pass-crossing days
• Trails are well established but exposed to weather at altitude, with sections of loose scree near the passes
• Pack horses or yaks carry camping equipment; trekkers carry only a daypack

Altitude Considerations

• A dedicated acclimatization day is built in at Jangothang (4,040m)
• Two passes above 4,800m are crossed on consecutive trekking days, so prior high-altitude experience is strongly recommended
• Altitude sickness is a real risk on this route; trekkers should be alert to symptoms and communicate openly with their guide

Physical Fitness Requirements

• Strong cardiovascular fitness built up over at least 2-3 months of training
• Multi-day trekking or camping-trek experience at altitude
• Comfort with 7-8 hour trekking days on consecutive days
• No technical climbing skills required, but sure-footedness on uneven, sometimes icy terrain matters

Who This Trek Suits:

• Experienced trekkers seeking a genuine high-altitude Himalayan challenge
• Travellers who have completed at least one prior high-altitude trek
• Those wanting a quieter, far less crowded alternative to Nepal’s classic treks
• Wildlife and landscape enthusiasts drawn to Jigme Dorji National Park
• Anyone wanting to pair a serious trek with meaningful cultural time in Paro, Thimphu, and Punakha

Spring (March to May)

Rating: Excellent  The most popular season for this trek, with blooming rhododendrons at lower elevations and generally stable pass conditions by late April.

Advantages:

• Clear mountain views of Chomolhari and Jichu Drake
• Rhododendron blooms along the lower trail
• Reasonably settled weather for pass crossings

Disadvantages:

• Early spring (March) can still see snow on the higher passes
• Busier season, so book well ahead

Summer/Monsoon (June to August)

Rating: Not Recommended  Heavy monsoon rain makes trails muddy and river crossings hazardous, and cloud cover obscures the mountain views the trek is known for.

Advantages:

• Lush, green lower valleys

Disadvantages:

• Passes can become dangerous or impassable
• Persistent cloud cover and leeches at lower elevations

Autumn (September to November)

Rating: Excellent  Widely regarded as the best season, with the clearest post-monsoon skies of the year and stable conditions on both passes.

Advantages:

• Best mountain visibility of the year
• Dry, stable trail conditions
• Comfortable daytime trekking temperatures

Disadvantages:

• Cold nights at high camps, particularly by November
• It’s a popular season, so early booking is recommended

Winter (December to February)

Rating: Not Recommended  Heavy snowfall closes Nyele La and Yeli La passes to trekking groups, making this route impassable for most of the winter.

Advantages:

• None is recommended for this particular trek

Disadvantages:

• Passes typically closed by snow
• Extreme cold at high camps

Recommendation: Late September through October for the most reliable pass conditions and the clearest mountain views. Late April to May is the best spring alternative once early-season snow has cleared from the passes.

Step 1: Assess Your Fitness and Experience

This is a demanding high-altitude trek. Be honest about your trekking background, and consider a shorter acclimatization trek beforehand if this would be your first time above 4,000m.

Step 2: Choose Your Season

Autumn and spring are the only viable windows. Decide between the clearer, colder autumn and the greener, potentially damper early spring.

Step 3: Secure Your Visa and SDF

All visitors must book through a licensed Bhutanese tour operator, who arranges your visa clearance letter and includes the Sustainable Development Fee in your package cost.

Step 4: Book International Flights

Paro is served by Druk Air and Bhutan Airlines from hubs including Kathmandu, Delhi, Kolkata, Bangkok, and Singapore. Book early for autumn dates, which sell out fastest.

Step 5: Arrange Travel Insurance

Confirm your policy covers high-altitude trekking up to at least 5,000m and includes emergency helicopter evacuation.

Step 6: Confirm Details and Deposit

A deposit of 30 to 50 percent is typically required to confirm your booking, with the balance due several weeks before departure.

Tips for First-Time Chomolhari Trekkers:

• Begin a structured fitness routine at least two months before departure, prioritising cardio and hill walking with a loaded pack
• Break in your trekking boots thoroughly before you arrive
• Pack for a wide temperature range, from warm valley afternoons to sub-zero nights at high camps
• Discuss any altitude concerns with your guide honestly and early

The Stunning Chomolhari Trek is Bhutan at its most elemental: nine days of glaciated peaks, wind-scoured passes, and valleys where yak herders still live much as they have for centuries, bordered on either end by the warmth and colour of Bhutanese valley life. It is not an easy trek, and it shouldn’t be undertaken lightly, but for trekkers with the fitness and experience to take it on, it delivers some of the most rewarding high-altitude scenery anywhere in the Himalaya, with a fraction of the crowds found on comparable routes elsewhere.

Come prepared, come patient, and Mt. Chomolhari will more than repay the effort.
