    StandoutExceptional marine biodiversity

    Onong’s House Reef, right off the resort jetty, is an easy dive to 19 meters. It’s perfect for a relaxed afternoon check-out dive or if you just want to potter around with your camera. We've often found frogfish and a few different species of octopus tucked away in the corals here. It’s a comfortable option for beginners or anyone looking for a low-key dive.
