Zong Raue Waterfall

Tucked into the forested interior of Koh Samui near the Ang Thong area, this jungle waterfall offers a quieter, nature-focused alternative to the island's busy beaches. The waterfall flows through dense tropical vegetation and, when conditions are right, provides a rewarding escape into the island's wilder landscape. It attracts visitors looking to trade sand and sun for shade, birdsong, and the sound of moving water. The experience is genuinely natural and undeveloped, which means visitors should come prepared for the terrain rather than a polished attraction. Reaching the falls involves navigating a steep, unmarked trail where tree roots and branches serve as handholds — sturdy footwear is strongly advised over sandals or flip-flops. Reviews note that the upper level of the waterfall is worth the extra effort, as stopping at the first, smaller cascade undersells the site. Water volume varies considerably by season, and the falls can appear modest during drier months such as March. Good to know: The waterfall is best visited during or shortly after the wet season (May to October) when flow is at its strongest. There is no formal path, no listed opening hours, and no official website, so visiting during daylight hours with a charged phone and GPS is recommended. Ask at your hotel for current trail and water conditions before heading out, and bring water and snacks as there are no on-site facilities.
