Just two kilometers away from Chiang Saen Lake is Phra That Doi Pu Khao which is believed to have been built by a king of Wiang Hirannakhon Ngoen Yang in the middle of the 8th century.
This riverside temple near Sop Ruak Market is located on a hill just before the Golden Triangle and offers a spectacular view of the Golden Triangles riverine and mountain areas. The vihan and crumbled chedis are the only visible remains of antiquities today.
