About East of Eden
East of Eden is a broad east-coast Similan reef with a shallow top, a long coral slope, and the kind of calm aquarium feel that makes it a standout when the park is open. It rewards slow drift diving with healthy hard and soft corals, sea fans, turtles, rays, sweetlips, and plenty of smaller reef life. Plan it as a boat-based reef dive with enough depth to stay interesting, and time it for the open season when water clarity is best and currents are usually manageable.

Respect the park closure, follow the boat line, and keep an eye on depth when the reef slopes away.
Access Restrictions
No diving during the monsoon closure; access resumes only in the park's open season and through approved boat itineraries.
Legal Notes
The site sits inside Similan National Park, so seasonal park closure and any site-specific restrictions govern access.
