The story
Na Muang 2 is the upper fall of the Na Muang system and, at about 80 metres, is widely reported as the highest waterfall on Koh Samui. 7 km round trip with around 260 m elevation gain, per one local source; other sources describe it as a shorter walk from a second parking area used by 4WD tours). The path is well-trodden but not maintained: expect mud, roots, slippery rocks, a few rope-assisted steep parts and a final boulder scramble.

The reward is a tall, multi-tier cascade in a rock amphitheatre with a smaller, rockier pool than Na Muang 1. Flow varies strongly with season - after a long dry spell the fall can shrink to a thin thread, while in monsoon months it is powerful but dangerous. Na Muang 2 has a documented history of serious accidents on its moss-covered rocks; do not climb the rock face.
Most sources say entry is free with about 20-30 THB parking; one local source reports a 50 THB entry fee and 30/60 THB parking (scooter/car) - treat fees as variable. Sturdy shoes, water and insect repellent are essential.
