Situated near the office of Koh Chang National Park, Thanmayom Waterfall is the largest waterfall in the island and also a major source of water for islanders. The four-tier waterfall has a historical significance to the locals as it was visited by two Thai kings in the early twentieth century. Even though the fall can be accessed throughout the year, it looks more picturesque in the cool season. Most people stay around the first and second tier of the fall because the path to the third and fourth tiers is too steep and slippery.
Klong Plu Waterfall is another popular tourist attraction for those who stay near Had Klong Prao or Had Kai Bae. The fall is only 3 kilometres from Had Klong Prao and reached by road. The first tier of the fall is the best spot for a dip or relaxation since it has a small pool under the canopy of lush green trees. Like Thanmayom Waterfall, Klong Phu Waterfall is at its best in the cool season which starts from November until February.
