Sai Yok Yai Waterfall is part of Sai Yok National Park. The falls are about 100 km from Kanchanaburi on highway 323. It is famous for its idyllic beauty which was once visited by King Rama V. The falls are widely celebrated in Thai poetry and songs. The falls flows from cliffs into Kwai Noi River. The park entrance is about 38 km north of Sai Yok Noi Falls, but the falls are hidden 3 km off the main road. You can go there by motorbike or bus. Bus travellers should get off at the national park sign, then flag down a passing car or face a long and dusty walk. Motorcycle taxis may be available.
