Northern Rocky - Mergui Archipelago

Northern Rocky, a modest limestone outcrop, sits a short skip west of MacLeod Island, about 50 km from Kawthaung. It looks a bit like a sail from the north, an unassuming start to a surprisingly vibrant wall dive. We love the colour here, especially if you’re into orange; cup corals and fan corals coat the rock face, and it’s a good spot to find hawkfish perched on gorgonians. The wall drops to around 23 meters before giving way to jumbled boulders. Currents can pick up, so it's best suited for intermediate divers, but it’s a solid dive for those who appreciate the smaller details and a splash of fiery colour.
