Ban Sop Ruak (Thai: บ้านสบรวก) is a village in Wiang subdistrict (tambon) of Chiang Saen District (amphoe) in Chiang Rai Province, northern Thailand. The village is situated at the confluence of the Ruak River and the Mekong River which form the tripoint border of Thailand, Myanmar, and Laos. This location has enabled it to be marketed to tourists as the "heart" of the Golden Triangle, as the area is popularly known.[1][2]
