Beacon Point runs along the south of Island 8 and is described as the longest reef in the Similans, with over 300 species of coral recorded on it, the widest range in the park. There is usually no current, which makes it one of the more relaxed dives in the island chain, and the coral holds enough small life to fill a dive without covering much ground.
Where it is and how deep
8.6432° N, 97.6532° EApproximate position — the dashed circle shows where the site lies; your operator's briefing has the mooring.
The dive
Massive granite boulders stand along the reef and form swim-throughs and canyons, so the dive alternates between open coral ground and passages between blocks. The normal depth band is 10 to 25 m, and the coral runs from shallow water down to about 30 m, which leaves the working level to the group rather than to the site. With no current to fight, the route is yours to pick and the pace is unhurried.
Reef sharks, leopard sharks and stingrays are the larger animals seen along the reef, with barracuda, fusiliers and snappers over it. The small life is the other reason to dive here: nudibranchs, scorpionfish and other critters are numerous across the coral, and a slow pass over one stretch of it returns more than a long swim along the whole reef.
