    StandoutExceptional marine biodiversity

    Koh Rang Ban That is a pretty chilled out spot, excellent for easing back into things or for newer divers. The depth rarely pushes past 11 metres, making it a comfortable dive where you don't feel rushed. We often spot a few different species of anemone fish, especially the feisty tomato clowns, tucked into their anemones, and we've regularly seen stingrays nestled in the sand. It's a gentle introduction to the Gulf of Thailand's shallower sites.
