Namtso is 240 kilometers from Lhasa. It is one of the three largest holy lakes in Tibet and is also a famous holy site for Tibetan Buddhism. The endless snow-capped mountain beside the lake is the Nyainqentanglha Mountain. On a beautiful day, the snow-capped mountains are reflected in the lake, giving a sense of peace and tranquility. There are numerous secular believers who come to Namtso every year on April 15 of the Tibetan calendar to celebrate the Saga Dawa Festival.
