Anita's Reef is a rolling reef slope on the east coast of Similan Island 5, running from a shallow 5 to 6 m down to around 25 m, with a huge rock standing in a sandy area at the bottom under hard and soft coral. A gentle current and a slope that can be dived at any level make it a common choice for the first dive of a Similan cruise.

The dive

The rock on the sand is what most of the dive is organised around, and with the current usually gentle the slope can be worked in either direction and the group can spend as long down there as it likes. The shallow ground at 5 to 6 m sits at the top of the slope, which is where a first dive of the trip normally finishes, sorting out weighting and cameras without cutting the dive short.

Turtles are regular here, stingrays and garden eels are out on the sand, and pelagic fish pass along the slope. On the small side there are tiny box shrimp and partner gobies for anyone working the sandy ground with a macro lens, and the sand between the coral repays a slow, low pass more than a long swim along the reef edge does.
