Bamsaru Khal Trek — Complete Guide (2026)
Vibe & Scenery
The Experience
Introduction
The Bamsaru Khal Trek is one of Garhwal's lesser-known crossover expeditions, connecting the forests around Dodital with the isolated valleys beyond Bamsaru Khal. Unlike popular trekking circuits, this route spends most of its journey in remote mountain terrain where long walking days, self-sufficiency, and changing weather become part of the experience.
After following the trail towards Darwa Pass, the expedition gradually leaves established trekking routes behind and enters increasingly rugged alpine landscapes of boulder fields, glacial moraines, snow slopes, and exposed ridgelines. Crossing Bamsaru Khal at around 15,100 ft is the defining challenge of the trek, rewarding trekkers with expansive views of the Bandarpoonch massif, Black Peak (Kalanag), and surrounding Garhwal ranges.
This is not a trek chosen for famous campsites or crowds. It appeals to experienced trekkers seeking a genuine wilderness crossing where route commitment, endurance, and mountain judgement matter as much as fitness.

Is the Bamsaru Khal Trek suitable for beginners?
Absolutely not. This is a difficult, high-altitude expedition crossing two major passes (Darwa at ~13,600 ft and Bamsaru at ~15,100 ft). It requires excellent cardiovascular fitness and prior experience with high-altitude treks.
Is this the same as the Dodital Trek?
Dodital is just the warm-up. While commercial Dodital treks end at the lake or Darwa Top and return, the Bamsaru Khal expedition pushes much further into the unmapped Bingad and Songad valleys to cross the Bamsaru pass.
What kind of terrain can I expect on the pass crossing?
The final climb to Bamsaru Khal involves navigating steep, unstable scree, boulder fields, and often deep snow depending on the season. The descent towards Songad is notoriously sharp and hard on the knees.
Are ropes required for Bamsaru Khal?
Usually, fixed ropes are not mandatory in the peak season (September). However, in early June, when snow is deep on the descent, guides may fix a safety rope for a brief section near the cornices of the pass.
Where is the last point of mobile connectivity?
You will lose all mobile network (BSNL/Jio) shortly after leaving Sangam Chatti. You will be completely off-grid for the next 6 to 7 days until you reach Sukki or Harsil.
Is Acute Mountain Sickness (AMS) a major risk here?
Yes. The jump to Bamsaru Base Camp (~13,500 ft) and the pass (~15,100 ft) poses a significant AMS risk. The itinerary is designed to acclimatize you at Dodital and Bingad first.
Are there river crossings?
Yes, particularly in the Bingad and Songad valleys. Depending on the snowmelt, these glacial streams can run high and freezing cold in the afternoons.
Why is this trek so rarely done compared to Roopkund or Goechala?
Bamsaru Khal is logistically complex, requires pristine navigation as trails disappear in the upper valleys, and lacks the commercialized infrastructure of popular routes. It is reserved for purists.
