Similan Dive Sites
Beacon Reef is a fringed reef that borders the whole eastern side of island 8 (Koh Similan), north of Elephant Head Rock.
Due to the lush coral, reef fish such as angelfish, butterflyfish, and moray eels are abundant here.Large schools of pelagic fish such as blue fin trevally, snappers, fusiliers, goatfish and longnosed emperors ca be seen here. At the wreck, swarms of batfish hang around curiosity close to divers. Lastly, in the shallow waters, turtles are frequent visitors.
In August 2002, the Atlantis X, a liveaboard vessel, sank near Similan Island 8.The Atlantis X (Rareung-Chon) was scheduled for a four-day trip to Similan National Park on 1 August 2002, which is during the area’s low season. Unfortunately, bad weather delayed her departure until 6:00 am the next day. After leaving port, there was a malfunction of the bilge pump, and the boat began to take on water.
Though the captain made an effort to return to port, the rapid pace of water entry forced him to head back to Similan Island 8 while calling for help. The Atlantis X sank that day, but luckily, all passengers and crew were safely evacuated to a nearby fishing boat.
This is a rather easy-going dive site, suitable as the second or third dive of the day or for a night dive wreck, as walkways and corridors are narrow.
