Sai Yok Yai Waterfall & National Park
Waterfalls flowing into the Kwai Noi River — Sai Yok National Park pairs forest swimming with Death Railway history and river rafting.

About this Place
Sai Yok National Park protects 500 sq km of forest along the Kwai Noi River and the Thai-Myanmar border, with Sai Yok Yai waterfall as its signature attraction. The falls cascade directly into the Kwai Noi River at the park headquarters, creating a photogenic scene where you can swim in the river below. Boat trips upstream reveal karst caves including Lawa Cave with ancient stalactites. The park shelters Kitti's hog-nosed bat — the world's smallest mammal. Rafting on the Kwai Noi River passes Death Railway remnants and jungle scenery. Bamboo floating raft houses on the river are available for overnight stays. Sai Yok is 100km from Kanchanaburi town and 15km from Hellfire Pass, making a combined day trip from Kanchanaburi practical.
