Live Your Best Lives
Basum Co, also known as Cogao Lake, means "green water" in Tibetan. It is located in a high gorge and deep valley in the upper reaches of the Ba River, more than 50 kilometers away from Gongbu Jiangda County in Nyingchi Prefecture. It is a famous sacred lake and holy place of the Red Sect (Nyingma Sect of Tibetan Buddhism).
Although Basong Co is hidden deep in a mountain valley with poor transportation and far away from towns, it is widely known for its lush forests and the clear water among the towering mountains, becoming one of the earliest known scenic spots in Nyingchi area.
About 100 meters from the shore lies a small island called Zhaxi Island. Legend has it that it's a "hollow island," meaning it's disconnected from the lakebed and floats on the surface. While this is just a legend, it's still incredibly fascinating. Try stomping your feet in certain spots to see if you feel a hollowness. The island also houses the Tang Dynasty-era "Cozong Gongba Temple," a renowned Nyingma sect temple in Tibet. Wooden carvings of male and female genitals flank the entrance. The god of fertility is the patron saint of plateau residents, protecting the health and happiness of themselves and their families.
The crystal-clear waters of Basongcuo Lake reflect the surrounding snow-capped mountains. In spring, the lake blooms with flowers, and the snow-capped peaks are reflected in the lake, creating a breathtaking sight. In autumn, the mountains and forests are bathed in crimson, and the sky is azure. The fiery red maple leaves reflect the brilliant sunlight, reflected in the azure waters of the lake, creating a breathtaking spectacle.
