The WWII Memorial Bridge spans the Pai River about 2 kilometres west of town. Built by Japanese forces using conscripted local labour during the Second World War as part of a supply route toward Burma, the bridge has become one of Pai's landmark sites. The current iron structure is not the original wartime bridge, which was burned by retreating Japanese troops in 1944, rebuilt afterward, and later destroyed by flooding; today's bridge is maintained as a memorial to that history.
The setting is the real attraction: a narrow bridge over the Pai River, with rice fields and mountains on all sides. It is particularly photogenic at sunset, and the approach road passes through open countryside typical of the valley. The bridge is about a 30-minute walk from the centre of town, or 5 minutes by motorbike.
