Tibet is known for its breathtaking sacred lakes, yet few places feel as enchanting and peaceful as Lake Basum Tso. Nestled deep within the forests and mountains of eastern Tibet’s Nyingchi Prefecture, this turquoise alpine lake combines natural beauty with rich Tibetan culture. Often overlooked by travelers who focus on Lhasa or Everest, Basum Tso offers a quieter, more intimate experience of the Tibetan Plateau.
Location and Geography
Lake Basum Tso, also called Basong Co, lies about 360 kilometers east of Lhasa, in Bayi District of Nyingchi. Sitting at an altitude of 3,480 meters (11,417 ft), it is surrounded by snowcapped peaks and thick pine forests, creating a striking contrast to the open, arid plateau landscapes more commonly associated with Tibet.
The lake stretches about 18 kilometers long and covers over 25 square kilometers. Fed by glacial meltwater, Basum Tso’s waters remain pristine, reflecting emerald and turquoise tones that shift with sunlight and seasons.

Cultural and Spiritual Significance
Basum Tso is not only a scenic treasure but also a sacred lake of the Nyingma School of Tibetan Buddhism. Legends say that Guru Padmasambhava, who brought Buddhism to Tibet, once meditated near this lake.
At the center of Basum Tso lies Tashi Island, a small but spiritually important site. The island is home to the Cuozong Gongba Monastery, a 600-year-old temple where monks continue daily practices. Pilgrims visit to spin prayer wheels, offer butter lamps, and circle the island in reverence.
Prayer flags around the shore and on the island flutter in the wind, symbolizing peace and blessings carried across the landscape.
