Khoun Kong Leng (Blue Lagoon)
ຂຸນກອງແລງ
An emerald lake fed by underground springs at the foot of limestone mountains, regarded as sacred, with swimming allowed downstream.
About 30 km north of Thakhek, the lake is fed by underground springs. Its water is clear and emerald blue, and it is surrounded by karst peaks and forest. Locals regard it as sacred. Swimming is forbidden in the lake itself, but you can splash around in designated areas downstream. The last ten-odd kilometers are a bumpy dirt road, muddy and hard going in the rainy season, so it is best to go in the dry season by motorbike or hired car. It can be visited as a standalone day trip from Thakhek.
