Why dive here
With 173+ marine species recorded in the area - including blacktip reef sharks, eagle rays, giant moray eels, whale sharks and clownfish - Turtle Ridge (Turtle Ledge) offers some of Similan Islands's richest reef diving. Water ranges 29-31°C, warmest April, May, June.
Turtle Ridge, or Ledge, as some call it, is one of those Similan sites we always make time for. Forget the name, it's not just about turtles, though you'll often find green and hawksbill grazing in the shallows. What we really love here is the sheer health of the hard corals, particularly the sprawling fields of staghorn. They stretch out, creating these intricate canyons and swim-throughs where we’ve found everything from two-toned pygmy squid clinging to a branch to the flash of a Dapple Coris darting through. Our favourite approach is usually a drift along the main reef, letting the gentle current carry us past dense schools of jacks that swirl and pulse. Keep an eye out for those subtly patterned dusky wrasse picking through the corals. If you're lucky, a whale shark might cruise by, but even without that big draw, the reef itself is vibrant. It’s a site that rewards a slow pace, letting you really appreciate the smaller details and the sheer volume of healthy coral. Perfect for divers who appreciate a robust reef and don't mind a leisurely exploration.
