Rocky pinnacle with swim-throughs and caves.
Nang Yuan Pinnacle is a rocky reef between Koh Tao and Koh Nang Yuan with swim-throughs, a small cave system, and a shallow finish that keeps the site interesting without turning it into a full technical wreck or deep wall. Soft corals, whip corals, sponges, turtles, stingrays, and schooling reef fish make it a scenic scuba stop that still demands careful route-finding.

Treat the swim-throughs and cave system as overhead features, keep a close eye on buoyancy, and use calm conditions to make route-finding easier.
Access Restrictions
Use a local boat operator and treat the swim-throughs and cave system as overhead features.

Scuba Diving
Boat-access reef dive with swim-throughs, a cave system, and a shallow finish toward Japanese Gardens.
Freediving
Not a freedive-first site because the swim-throughs and cave system sit on a scuba-oriented profile.
Snorkeling
Snorkelling is better on the island's shallower reef sites; the pinnacle itself is mainly a scuba objective.
