About Haew Narok Waterfall
Haew Narok is the park's tallest waterfall, a three-tier cascade tucked on the southern edge. When it's running full after the rains, it's a genuine spectacle and worth the effort to reach.
That effort is real, though. It sits on the far southern side, so from the Pak Chong side you're either driving through the whole park or looping around via the southern gate, then walking in and taking a long staircase down to the viewpoint. You'll feel the climb back up. In the dry season the drop shrinks a lot, so save this one for the wet months.
There's a memorial here to a tragic wild-elephant incident, and the top of the falls is dangerous. Stay behind the barriers and keep an eye on kids.
Highlights
- Khao Yai's tallest waterfall, a three-tier drop

- Quieter, wilder southern corner of the park
Tips
- Go in the wet season; the drop is far less impressive when dry.
- Budget energy for the long staircase and the climb back up.
- Stay behind the barriers, the top of the falls is dangerous.
- It's a long haul from the Pak Chong side, so plan the drive.
How to get there
From Pak Chong it is on the far southern side of the park: drive through the park (~1.5 hr) or loop around via the southern (Nakhon Nayok) gate. Then a ~1 km walk and stairways down to the viewpoint. Car or hired driver essential.
