Nan Long Boat Racing Festival in Nan
Nan province's long-boat racing festival, held on the Nan River each October or November around the end of Buddhist Lent, is known for its hand-adzed dugout boats carved with elaborate naga serpent motifs. Crews of up to fifty or sixty rowers compete in a tradition tied to the region's Tod Kathin and end-of-Lent observances.
Nan province sits in a mountainous pocket of northern Thailand, and its long-boat racing tradition grew directly out of the practical geography of the Nan River, which for centuries served as a primary transport route through terrain otherwise difficult to cross.
