About Than Mayom Waterfall
Than Mayom Waterfall is a four-tier waterfall on the eastern side of Ko Chang Island in Trat Province, within Mu Ko Chang National Park. Fed by streams from the island's central mountains, it flows over rock terraces into pools surrounded by tropical forest. Notable for royal visits by King Rama V, Rama VI and Rama VII, it is one of Ko Chang's most historically significant and accessible waterfalls near Than Mayom Pier.
Visitors guide
Visitors can expect a short forest walk from the parking area to a series of four cascades flowing over wide rock faces into clear pools. The lower tiers are easily accessible with pools suitable for wading and swimming when water levels permit, while upper tiers require scrambling over rocks and roots. The site is set in dense evergreen forest within the national park, with shaded paths, rock inscriptions, and viewpoints of the cascade and surrounding jungle.
