SEA CRAB - Similan Islands

Sea Crab, a small barge that went down in '75, sits in just a couple of metres of water. It's a proper rust bucket now, completely colonised by small reef fish and soft corals. You won't be doing much penetration here, but it's great for peering into crevices where you might spot juvenile snapper or a moray eel tucked away. Honestly, it’s more of an interesting snorkel than a dive, or a quick safety stop at the end of a deeper Similan dive.
