    StandoutExceptional marine biodiversity

    Manta Bay at Racha Noi is a mellow spot, good for those looking for a relaxed dive. We’ve found the coral reef here is quite pretty, with a nice spread of hard and soft corals that hold a surprising number of smaller reef fish. It’s a comfortable 16-meter maximum depth, making it ideal for newer divers or anyone wanting a longer bottom time. Keep an eye out for blue-spotted rays resting on the sandy patches; we often spot them just cruising past.
