Anita's Reef on the sheltered east side of Similan Islands 5 and 6; island outlines from OpenStreetMap (where the names Ko Ha and Ko Hok Noi appear swapped against the dive guides, which put Island 6 (Ko Hok) to the north and Island 5 (Ko Ha) to the south). Contours, bommies and boulders around the two OSM islands; the big bommie, 12 m on top and 20 m at the base, the entry at the south-east edge of Island 6 and the boulders in the deeper south from Similan Diving Tours and Andy's Scuba Diving. The site coordinates (8.57713, 97.64635) are 400 m north of the islands in open water; the origin is moved to the reef east of the islands (8.5717, 97.6465), in line with divezone. Positions are approximate.

Anita's Reef runs from the south-eastern tip of Similan Island 6 around the east side of Island 5 — the sheltered side, which makes it the opposite of the western boulder sites. A gently shelving coral slope, white sand, granite boulders to the south and in the deeper water, little current and excellent visibility.

The centrepiece is a single very large coral bommie standing on the sand, covered in soft coral and absolutely full of fish. It is the standard last-dive-of-the-day site and also the standard first-dive-of-the-trip site, for the same reason: nothing about it is difficult.
