Animal Pass Trek — Complete Guide (2026)
Vibe & Scenery
The Experience
Introduction
Hidden beyond the popular villages of Tosh and Pulga, the Animal Pass Trek ventures into the remote glacial landscapes at the head of the Parvati Valley. The trail gradually leaves behind forests and shepherd camps before entering a world of moraines, boulder fields, and ice-carved terrain surrounding the Tosh Glacier.
Throughout the journey, trekkers enjoy spectacular views of major Himalayan summits including Papsura and White Sail, two of Himachal Pradesh's most prominent peaks. The combination of sustained altitude gain, rough terrain, and glacier travel demands good fitness and previous high-altitude trekking experience.
Although far less famous than neighbouring expeditions such as Pin Parvati or Sara Umga, Animal Pass offers a rewarding wilderness experience for trekkers seeking quieter routes in the Parvati Valley.

→ See full itinerary with altitude profileDifficulty & Fitness
Rated challenging. The first two days are standard alpine trails. However, approaching Shamshi Thach and the push to Animal Pass involves brutal, unstable glacial moraine (boulder hopping) which is extremely exhausting and requires intense focus.

→ See full cost breakdownFrequently Asked Questions
Is the Animal Pass trek suitable for beginners?
No. This trek is graded Moderate to Challenging. It requires navigating steep glacial moraines, boulder fields, and reaching an altitude of 15,000 feet. Prior high-altitude trekking experience (above 12,000 ft) is highly recommended.
Why is it called Animal Pass?
The pass earned its name because local shepherds historically used this route to guide their flocks of sheep and goats over the ridge during the summer grazing months.
Will we actually walk on the Tosh Glacier?
The trail takes you to the snout and the lateral moraines of the Tosh Glacier. Walking directly on the main body of the glacier is highly dangerous due to hidden crevasses and requires roped mountaineering travel, which is not part of this standard trekking itinerary.
What are the main hazards on this trek?
The primary hazards are Acute Mountain Sickness (AMS) due to the 15,000 ft altitude, twisted ankles on the unstable boulder moraines near Shamshi Thach, and unpredictable, rapid weather changes characteristic of the Parvati valley.
Is there mobile connectivity on the trail?
You will get network coverage (Jio, Airtel, BSNL) in Kasol and sporadically in Tosh. Once you leave Tosh and enter the Buddhaban forest, there is zero mobile network for the remainder of the trek.
What is the best time to do this trek?
The best window is from June to mid-September. Unlike many other Himalayan regions, the Parvati valley is highly scenic during the monsoon, though trekkers must be prepared for rain in the lower sections.
Where is the nearest medical help?
The nearest basic medical dispensary is in Barshaini/Kasol. For serious emergencies like HAPE or HACE, evacuation must be done to the major district hospital in Kullu, which is several hours away by road from the trailhead.
Can I do this trek solo?
Absolutely not. The trail above Buddhaban is completely unmarked, the boulder fields are confusing, and the isolation means a rolled ankle could be fatal if alone. Always trek with a certified local guide.
