    StandoutExceptional marine biodiversity

    Marista Rock is a granite pinnacle, typical of the Similans, with large boulders creating swim-throughs and shelves. It’s a good spot to find lionfish tucked into crevices and occasionally a leopard shark resting on the sand flats. The site is relatively exposed, so we often experience moderate currents, making it better suited for divers with some experience. Visibility usually sits around 20-25 metres.
