Na Muang Waterfall  : -

Na Muang Waterfall is located between Hua Thanon and Nathon in the Southwest sector of the island just off a concrete road at Ban Thurian, making it easily accessible to visitors.

Rocks and tree roots form a natural staircase leading directly to a large pool at the base of the waterfall. Be careful when diving or swimming in the pool, however, as shallow, sharp rocks are obscured by the frothing falls.

Na Muang Waterfall actually consists of two waterfalls: while the one accessible by road is 18 meters high, Na Muang 2 is about 80 meters high and can only be reached by a 30 minute walk. The waterfalls are the most scenic on the island and well worth a visit to Samui's "interior".
