Why Visit This Place?

Sai Yok National Park is a natural escape famous for its scenic waterfalls, limestone cliffs, and dense jungle along the Kwae Noi River. Known for the peaceful Sai Yok Yai Waterfall, the park combines lush beauty with a laid-back atmosphere. It’s a great option for travellers who want a slower paced day surrounded by nature, with the option to explore caves and historic sites linked to the Death Railway.

What to Expect

The park’s most accessible attraction is Sai Yok Yai Waterfall, cascading directly into the river. Visitors can enjoy shaded picnic areas, walking paths, and boat trips on the Kwae Noi. Wildlife lovers might spot hornbills, bats, or the rare Kitti’s hog-nosed bat in nearby caves. The park also features remnants of the Death Railway line, including a section of track and wartime artefacts.
