    StandoutExceptional marine biodiversity

    Jansom Bay is a solid choice for a relaxed afternoon dive, especially if you’re new to the underwater world or just getting back into it. Dropping to a gentle 8 meters, the coral gardens here are good for a slow poke around. We often spot pipefish tucked into the anemones and clownfish darting amongst their tentacles. It’s a great spot to practice buoyancy and get comfortable, without strong currents to worry about.
