The Pin Bhaba Pass Trek is one of Himachal Pradesh’s most stunning and dramatic crossover treks, offering a rare opportunity to experience two distinct Himalayan landscapes in a single journey. The trail connects the lush green valleys of Kinnaur with the stark, high-altitude deserts of Spiti, creating an unforgettable contrast of scenery and culture.
Starting from the quaint village of Kafnu (2,350 m), the route follows the Bhabha River through dense pine and deodar forests, vibrant alpine meadows, and high-altitude campsites such as Mulling, Kara, and Phustirang. The highlight of the trek is crossing the Pin Bhaba Pass (4,915 m / 16,125 ft), a vantage point offering panoramic views of snow-clad peaks on one side and the colourful, barren mountains of Spiti on the other.
The descent leads into the Pin Valley National Park, home to rare Himalayan wildlife and unique flora, before reaching the picturesque Mudh Village (3,810 m) in Spiti. The trek concludes with a scenic drive to Kaza, the cultural and commercial hub of Spiti Valley.
With a moderate difficulty level, diverse terrain, and unmatched natural beauty, the Pin Bhaba Pass Trek is perfect for trekkers seeking both adventure and the unparalleled visual diversity of the Himalayas.

The day’s trek takes you from the serene forested campsite of Ghairoli Patal into one of the most breathtaking alpine meadows in the country — Aali Bugyal. The trail begins with a gentle ascent through dense oak and rhododendron forests, where the fresh mountain air and occasional bird calls create a soothing start to the day.
As you climb higher, the tree line gradually recedes, and the landscape opens up to vast, undulating grasslands. The first sight of Aali Bugyal is truly magical — rolling green meadows stretching as far as the eye can see, framed by a stunning panorama of Himalayan peaks including Nanda Ghunti and Trishul.
These high-altitude pastures, dotted with wildflowers in summer, are a photographer’s paradise and an ideal spot to rest, soak in the views, and enjoy the surreal silence of the mountains.

Snow-capped ridges loom closer as you gain elevation, offering spectacular views of the Hansbeshan Peak and surrounding ranges. Small glacial streams and boulder-strewn patches make the trail more challenging. By afternoon, arrive at Phustirang, a high-altitude campsite nestled below the Bhabha Pass, encircled by dramatic mountain walls—your base for the upcoming pass crossing.
In case of bad weather, natural delays, or other unforeseen difficulties, Day 5 is reserved as a Buffer Day. This will only be used if conditions at the last minute prevent the itinerary from continuing as planned.
⚠️ Important Note:
Trekkers are advised to plan their travel keeping the buffer day in mind.
If the buffer day is utilized, an additional fee of ₹2,000 + 5% GST per person will be charged.
