Beacon Reef lies on the east side of the island and has the longest reef in the Similans This is a great check out or night dive as the gentle slopping reef runs down to around 22 meters. With lots of hard and soft corals the reef fish here are in abundance with the lion fish and moray eels hiding in the holes.
A glance out in to the blue can prove rewarding with large dog tooth tuna and trevallys darting in to the reef to feed on the small bait fish. This is also the location of the Atlantis Wreck resting on the sloping coral wall from 12-32 meters. The wreck is packed with fish life and makes for more great photography.
