Beacon Reef – Eastern Side of Similan Island #8 Map and description

Beacon Reef Dive Site Map from the Similan IslandsDive Beacon Reef

A reef that extends the whole eastern side of Island 8 (Koh Similan). Typical of most of the Similans – this a sloping reef running from 8 meters (25 feet) to 30 meters (100 Feet). Fields of staghorn, brain and bushy corals mark this site. You’ll certainly find moray eels, batfish, Snappers and more.

The main attraction at this site is the wreck in the middle! This was a liveaboard that sank in 2002 after a bilge malfunction. All the crew and customers escaped without injury. They tried to save the Liveaboard from sinking, by ramming the reef! Aside from pure stupidity, it also damaged the reef in the shallows and then as it sank toward the deep, it ripped the coral apart. Happily the very same company, after this shining example of brilliance, sank another Liveaboard by hitting Richelieu rock a few years later.

Diving depths range from 8-30 meters (25-100 feet) with the main diving done at 15 Meters (50 feet).

Currents are light, generally helping rather than hindering.

Visibility is pretty good (unless we get thermoclines) – 20 meters (75 feet).

Dive site is accessible to all levels of divers.

Bleaching at Beacon Reef

In March and April 2010 the Similan Islands suffered from a naturally occurring event called the Reverse Indian Ocean Dipole. This is very similar the “La Nina” that changes water temperatures and currents in the Pacific ocean. In this case, the water temperatures in the entire Andaman Sea were raised between 2 or 3 degrees above median. This was enough to damage the living corals in shallower sites and those with limited tidal interchange. On the Western facing side of the Similan National Park, the affect on the sites was minimal. On the shallow sloping reefs of the Eastern side , there was a more noticeable impact on the corals. His has caused some bleaching, and on two of this sites a – a noticeable impact. The National Park system shut down several sites throughout the Andaman region to protect the reefs from potential human impact (diving, snorkeling and fishing). These sites are already showing regrowth and at least two of the sites have re-opened at this time. Beacon reef was affected by this climactic event and is recovering.

Plus understand that the bleaching is not the result of direct human impact, or over use. It is the results of vast climactic changes that are happening on our globe. The reefs are accustomed to these temperature changes and can easily adapt and regrow. They can not regrow from the damage done to them physically or chemically by inconsiderate divers and snorkelers.

As with all dive sites in the Similan Isiands, it is strongly recommended that you go with only registered and reputable dive operations, carry suitable travel insurance that covers diving accidents and evacuations as well as trip cancellation insurance due to the potentially erratic weather conditions.
