This route covers 133km return.It involves around 4,750m of cumulative elevation gain.
The route reaches roughly 4,890m at its highest point. Proper acclimatization is strongly advised for this high-altitude journey.
Technically, the The Chomolhari Trek standard trail is challenging. The primary difficulty is the sustained physical effort required or technical terrain features.
Overview
Technical Summary
The Chomolhari Trek is a 7–9 day high-altitude route through the Jigme Dorji National Park, Bhutan. The trail traverses from Drugyel Dzong toward the base of Mount Jomolhari (7,326m), a sacred peak for the Bhutanese people.
Proximal Glacial Topography. The defining characteristic is the proximity to the vertical faces of Jomolhari and Jichu Drake from the Jangothang base camp. The route provides an observation of the vertical ecological transition from rhododendron forests to permafrost environments. The convergence of multiple glacial valleys at Jangothang offers a perspective on the scale of the Himalayan range and the traditional herding livelihoods of the Layap community.
Hazard Assessment
Sustained exposure above 3,500m and multiple pass crossings at 4,700m+. Risk of Acute Mountain Sickness (AMS) and high-altitude pulmonary/cerebral edema is a primary objective hazard.
High passes are subject to rapid weather shifts including blizzards and extreme wind-chill even during peak seasons.
Potential altitude-related conditions include AMS, HAPE, and HACE. Adequate acclimatization is essential.
The Expert Take
Success on this route requires balancing physical stamina with environmental awareness.Local conditions shift rapidly; always verify forecasts with regional authorities before moving to higher ground.
Stage Breakdowns
Approach & Acclimatization

Technical Profile
Vertical Ascent Profile
Significant cumulative vertical movement over 9 days. The profile involves a steady ascent through forested valleys followed by several high-pass crossings and sustained high-altitude plateau transit.
Terrain Characteristics
Scramble terrain (Class 2) — involves fixed-rope sections or mandatory hand-use on steep terrain.
The cumulative energy expenditure for The Chomolhari Trek represents a significant physical commitment. Success requires adequate preparation and moisture management.
