Sai Yok National Park Tours and Activities

Encompassing 193 square miles (500 square kilometers) of limestone mountains blanketed in deciduous, dry evergreen and bamboo forest, Sai Yok National Park attracts hikers to its caves, waterfalls and rare wildlife. The park’s most famous attraction is the Sai Yok Noi waterfall, a cascade along the Khwae Noi River near the terminus of the famous Death Railway.

The park is also famously home to the world’s smallest mammal, the thumb-sized Kitti’s hog-nosed bat, which can be spotted in a series of caves about a mile (2 kilometers) past Sai Yok Noi. Other fauna in the park include Rachinee crab, sambar deer, guars, water monitors and wild pigs.

For those who wish to stay within the park, accommodation options include campgrounds (with tents for rent), bungalows and private raft resorts floating on the Kwai Noi River. None are equipped with electricity.
