Anemone Reef - Similan Islands

Anemone Reef in the Similans isn't just about the anemones, though there are plenty and they’re gorgeous. We love dropping in on the north side, letting the current carry us gently along the shallow reef top. That’s where the light plays beautifully, picking out all the tiny critters. Keep your eyes peeled for those blennies peeking out of every crevice, especially the Spotty Blennies – they have so much character. The real show, though, is the sheer density of fish. Schools of cardinalfish shimmer, and if you look closely into the anemones, you’ll often find cleaner mimics darting amongst the tentacles. Down deeper, around the base of the pinnacle, watch for the larger rock cods lurking. It's a busy site, yes, but for good reason. We’d suggest going early if you can manage it; the morning light really makes the colours pop and you beat the rush. It’s an easy, colourful dive, perfect for photographers or anyone who just loves to drift and absorb the sheer vibrancy of a healthy reef.
