    StandoutExceptional marine biodiversity

    Coral Island, also known as 데블스 마이톤NO2, is a good spot for easing into the Similans, particularly if you're a newer diver or just want a relaxed second dive. The reef here stays shallow, topping out at about 15m, which gives you plenty of bottom time to explore. You’ll find healthy hard corals blanketing the seabed, with parrotfish and angelfish weaving through them. It's a nice, gentle drift over the coral bommies, perfect for spotting smaller reef inhabitants without feeling rushed. We often see sweetlips schooling under the ledges, and sometimes a relaxed reef shark cruises by in the deeper blue.
