The Pin bhaba pass trek is one of the most dramatic crossover treks in Himachal Pradesh, connecting the lush green Bhaba Valley in Kinnaur to the stark desert of Pin Valley in Spiti. Rising to an altitude of 4,915 meters, it offers a thrilling transition from dense forests and alpine meadows to barren, multicolored mountains. The trail begins from Kafnu and concludes at Mudh Village, covering roughly 50–60 km over 7 to 8 days. Rated moderate to difficult, it’s ideal for trekkers with prior high-altitude experience. Campsites like Phutsirang are scenic highlights, offering surreal views. The best time to undertake this trek is from July to early October, when conditions are favorable. It’s perfect for those seeking raw Himalayan beauty and solitude.
