The Boon Ko Ku So Bamboo Bridge stretches about 800 metres across rice paddies and over the Pai River roughly 3 kilometres west of town. Originally built by monks to allow villagers to reach the local temple, it has become one of the most photographed spots in the Pai area. The walk across takes about 15 minutes and passes over wooden platforms, bamboo sections, and along a path through fields.
The bridge is best in the early morning when the mist still sits in the valley and the light is soft on the rice fields. Admission is modest. The surroundings — flat paddy fields against the mountain backdrop — are particularly striking in the green season (July–October) when the rice is growing. The bridge is rebuilt each year after flooding takes out sections, so conditions vary.
