About Than Sadet Reef

Than Sadet is famous for its waterfall that Thai kings have visited for centuries. The reef at the beach below is modest but combines nicely with a waterfall hike for a full day of nature. Snorkeling is best in calm months when the east coast is protected.

Tips

Hike the waterfall trail first, then cool off with a snorkel. Only accessible in calm weather.

Experience Required

None.
