Recently opened to foreigners due to the proximity of the Chinese boarder, the Changthang is a land of wilderness and magnificent landscapes. This region is characterized by high arid plains, remote villages, snow-capped peaks and beautiful high altitude azure-blue lakes, the largest being Tsomoriri at 4,500 m. Truly remote, this area is only accessible for a few months every summer and is inhabited by Changpas - nomadic yak and pashmina goat herders of Tibetan origin, who wander this area crossing over high altitude mountain passes. Our trek will take us across these passes to their summer settlements to witness a unique human culture, far away from the reaches of the modern world. The itinerary then goes south towards Spiti, following the western bank of the lake. The scenery is wild and vast with snow-capped peaks lining the far horizon. The trek ends at Tabo, famous for its monastery.
