Manaslu Tsum Valley Trek: 24-Day Larke Pass & Mu Gompa Expedition
A remote, culturally Tibetan high‑altitude trek through the Tsum Valley and over the Larke Pass, this 24‑day route links ancient gompas, yak pastures and panoramic Himalayan views. Plan for sustained altitude gain, basic teahouse stays and mandatory permits.
The Experience
Before You Go
Acclimatize on schedule
Follow the itinerary’s rest days (Samagaun, Mu Gompa) and ascend slowly—don’t skip acclimatization hikes.
Layer for volatile weather
Bring a warm puffy, waterproof shell and thermal base layers—conditions can shift from sun to snow within an hour.
Respect permits and checkposts
Tsum Valley requires special permits—carry originals and copies and register at checkpoints when required.
Drink and eat regularly
High-altitude hiking increases fluid and calorie needs—sip frequently and aim for salty, energy-dense snacks.

Conservation Note
The route runs through fragile alpine ecosystems and requires permits and conservation fees; stick to trails, pack out waste where possible, and support local lodges to sustain communities.
Tsum was a once-restricted, culturally Tibetan region opened to outsiders only in 2008; monasteries here preserve centuries-old Buddhist practice and local clan traditions.

Common Questions
Do I need a special permit for the Tsum Valley?
Yes—Tsum Valley is a restricted area requiring a special permit in addition to the Manaslu Conservation Area and TIMS permits; these are arranged before or at the trailhead checkpoint.
How hard is the Larke Pass?
Larke Pass is long and exposed at 5,213 m; it’s not technically technical in summer but snow, wind and low temperatures make it strenuous and potentially hazardous without proper gear and acclimatization.
What accommodation can I expect?
Teahouse and lodge accommodation is basic—shared rooms, simple meals, cold showers or none at higher elevations; bring a warm sleeping bag and patience.
When is the best time to go?
Autumn (Sept–Nov) and spring (Mar–May) offer the most stable weather and clearer views; winters see heavy snow and many teahouses close.
