Phou Asa is reached by a short walk or elephant ride from the village along a forest trail. The summit opens out to provide a stunning view over large areas of southern Lao. The forests of Xe Pian and Dong Hua Sao NPAs appear to stretch out endlessly from the Kiet Ngong wetland. To the north is the Bolaven Plateau, and on a clear day waterfalls can be seen cascading from it. Ahead to the east is the Xe Khong floodplain in Attapeu, and lining the horizon is the Annamite Mountains on the Vietnamese border. At the top of the outcrop is a ring of stone pillars. Legends abound about these remains, but it is unknown if the structure was built for religious or military reasons.
