Waterfall Bay is a small bay in the Similan Islands whose coral reef slopes down to a maximum of about 20 m. It is a hard-coral site, its slope built of porites, staghorn, table and brain corals, and a shallow, relaxed reef dive.
Where it is and how deep
8.6622° N, 97.6390° EApproximate position — the dashed circle shows where the site lies; your operator's briefing has the mooring.
The dive
The average depth here is 10-15 m, and most of the dive is spent at that level over an abundance of hard coral: pore coral, stag horn coral, table coral and brain coral. Below it the reef keeps sloping down to its deepest point at about 20 m.
