Than Sadet Waterfall

Than Sadet Waterfall is one of Ko Pha-ngan’s most historically significant natural sites, set within Than Sadet–Ko Pha-ngan National Park. Rather than a single dramatic drop, it is a series of granite cascades and pools flowing through dense forest to the sea. The area is known for its royal connections, with inscriptions commemorating visits by Thai kings. Visitors who enjoy short walks, a quiet natural setting, and a place of cultural interest may find it rewarding, especially in the wetter months when the water flow is stronger.
