The Parang La trek is an adventurous and challenging trekking route that was a traditional ancient route followed by traders from Spiti Valley, Ladakh and Tibet. For centuries, traders from Changtang and Rupshu conquered this unforgiving trail to attend the famous Ladarcha Fair in Spiti Valley. The trekking part starts from Kibber, one of the highest villages in the world, and takes you through the ancient route to Tibet, over the Parang La at 5600 meters. The trail winds up along the banks of the Tso Moriri Lake, which is located in the Rupshu area of Ladakh at an altitude of over 4500 meters. The Lake is well known for Bar-headed geese, black necked crane and Brahminy Ducks. One can also see Marmots and Kiang (wild ass) along the lake. The Parang La Trek ends at the village of Karzok – situated on the West Bank of the Tso Moriri Lake at an altitude of over 4500 meters. Karzok is home to a Buddhist Monastery belonging to the Drukpa lineage and nomads who trade in Pashmina wool and salt.
