Anita’s Reef is the east-side Similan reef between islands 5 and 6, with a shallow sandy start, coral bommies, and rich reef life. It is currently listed as indefinitely closed, so treat it as reference information rather than an active dive plan.
Conservative baseline from public research. No community dives logged yet.
Depth range, seasonality, and planning context.
Reported Depth
5m - 40m
Depth Note
A shallow sandy shelf drops into coral and sand, so the site functions as a long slope rather than a wall.
Best Season
Nov-Apr
Typical Conditions
A gently sloping reef with sandy patches, scattered boulders, and mild currents; historically an easy Similan dive.
Hazards, restrictions, and access requirements.
Safety Notes
The site has historically gentle currents, but closure status means it should be treated as reference material rather than a live dive target.
Access Restrictions
Boat access only in the Similan Islands, and the reef is currently listed as closed.
Legal Notes
The reef is listed as indefinitely closed; do not plan a dive there without checking current park notices.
Community notes to help plan your visit.
Scuba Diving
Historical profile is a long reef slope with shallow sandy start and deeper boulder/sand sections, which made it a good easy first-dive shape.
Freediving
Not a prime freedive target because the profile quickly runs into deeper water.
Snorkeling
Not a snorkel-first site; the reef quickly moves into scuba territory.
