This is the tallest waterfall on the island. It is located in Thansadej National Park and is made up of two parts, the Phaeng Noi (small waterfall), which is easily walkable from the entrance and Phaeng Yai (large waterfall) which is a pretty steep climb for about 250 meters up the mountain.
Like all the waterfalls on Koh Phangan, during dry season, this waterfall may have little or no water falling from it, which can be disappointing. Go during the rainy months and you’ll see the falls, during summer months, it is chancy but still a beautiful hike, nonetheless.
