The Thanlyin River (Salween River) is about 2,815 kilometers long, flowing from Tibetan Plateau into the Andaman Sea in the territory of China, Myanmar and Thailand. Its extensive drainage basin supports a biodiversity comparable with the Mekong and about 7 million people live in this region. The local people are quite isolated from the rest of Myanamar.

Timber harvesting has been beginning on the mountains surrounding Thanlyin River since the late 20th century, which causes various damages to the ecosystem of the river.

Crossing the bridge over the river, you can visit to Thanlyin Town, once a trading port occupied by the Portuguese in early 17th Century, and then discover Thanlyin colorful local market, Kyauktan Yele Pagoda.
