Sai Yok National Park
The Sai Yok National Park is situated about 100 kilometers northwest of Kanchanaburi along the Khwae Noi river, extending to the Myanmar border. Established in 1980, it covers some 500 square kilometers of limestone mountains, forest, and the river.The most visited is the approximately 15-meter-high Sai Yok Noi waterfall, right by the main road. About 40 kilometers further, by the park administration, is the Sai Yok Yai waterfall, plunging directly into the river over a rock edge. You can cross to the other bank via a suspension bridge.Some of the park's limestone caves are home to the Kitti's hog-nosed bat, the world's smallest mammal at about 2 grams. The largest cave is Tham Lawa, approximately 500 meters long. Along the river, remains of a Thailand-Burma Railway bridge and a Japanese camp have also been preserved.
