Koh Phangan / Than Sadet

Than Sadet Waterfall

A waterfall in Koh Phangan's national park area with a royal connection: four kings of the Chakri dynasty inscribed their names on a rock nearby, and King Chulalongkorn visited 14 times. It is a calm, nature-focused side of the island; the roads can be steep and unpaved, so avoid riding a motorbike if you are not used to them.
