Cockscomb Island - Mergui Archipelago

Cockscomb Island, just a couple of hours from Kawthaung, is a curious spot often chosen for a last, easy dive. We're talking about a limestone island with a lagoon tucked inside, accessible through several low openings in the rock. It's a shallow dive, maybe two to three meters deep, where you fin through these narrow passages into a sunlit natural pool. Inside, it's mostly rock walls and a calm, protected environment – more of a unique geological experience than a coral bonanza. Think schools of small fish flitting in and out of crevices and the cool feel of the rock. It's perfect for a relaxed finish to a trip, especially if you appreciate interesting topography.
