Zong Raue Waterfall
A genuinely undeveloped jungle waterfall near the Ang Thong area in western Koh Samui. There is no formal path - visitors climb a steep natural slope holding roots and branches, so sturdy footwear is essential. The upper level is worth the extra effort.

The story
Zong Raue is one of Koh Samui's least developed waterfalls, hidden in the forested interior near Ang Thong sub-district on the island's west side. There is no built path, no opening hours and no facilities: reaching the falls means climbing a steep, unmarked natural slope where tree roots and hanging branches serve as handholds. Reviewers advise sturdy footwear rather than sandals, and note it can be difficult for older or younger visitors - the upside is that you may have the falls to yourself.

Stopping at the first, smaller cascade undersells the site; the upper level is considered worth the extra scramble. Water volume varies strongly by season: best during or shortly after the wet season (May-October), and possibly underwhelming in drier months such as March. 3/5 (225 Google reviews on the May 2025 listing).
Because there is no signage or official management, ask locally about current trail and water conditions, go in daylight, carry water and a charged phone, and tell someone your plan. Some Google reviews for the map listing reference a zipline operator nearby; that is a separate commercial activity, not the waterfall itself.
