StandoutExceptional marine biodiversity

High Rock, often the first taste of Myanmar's Mergui, really throws you into the thick of it. We usually drop in on the north or east side, where the wall descends, giving way to a more gradual rocky reef as you round the south. The sheer volume of blue-lined snapper here is what grabs you – thick schools that move as one, occasionally parting to reveal giant moray eels peeking from crevices. We’ve also spotted plenty of cuttlefish here, often out in the open, not shy at all. It’s a great site for getting your eye in, a solid introduction to the energy of the Mergui.
