Than Sadet and the Royal Stones

Koh Phangan

Best Time to Do This

Dry season on the Gulf coast (December to August) for the easiest hiking conditions and best stream flow without flash-flood risk from heavy rain.

What to Expect

A stream running through Koh Phangan's east-coast jungle, notable for large granite boulders carved with the royal monograms of several Thai kings — Rama V, VII, and IX among them — who visited and swam here personally, a genuine royal heritage site rather than a manufactured one. The walk in follows the stream past natural pools suitable for swimming.

How to Prepare

Sturdy shoes with grip are essential — the trail involves scrambling over wet granite, not a flat path. As with any site bearing royal insignia, treat the carved stones with visible respect; climbing directly on the royal monograms themselves is inappropriate.
