About Ton Sai Waterfall
Ton Sai sits on the west side of Khao Phra Thaeo and doubles as the trailhead for the nature trail that crosses the reserve toward Bang Pae. Like its sibling, the waterfall itself is best after rain and underwhelming in the peak dry months.
The real draw here isn't the falls, it's the forest. The walk and the birdlife are what make the trip worthwhile, and the full cross-forest trail is a proper hike if you're up for it.
Come for the rainforest experience rather than a dramatic cascade and you'll enjoy it.
Highlights

Tips
- Come Jun–Dec when the flow is stronger
- The forest walk and birdlife are the real draw
