Anita's Reef - Similan Islands

Anita's Reef, tucked away on the eastern side of Similan Island No. 5, is a site we often suggest for a relaxed dive. The gentle sandy slope makes for easy navigation, and it's punctuated by some seriously impressive coral bommies. You'll find a nice mix of table and staghorn corals, and we’ve often spotted lionfish lurking, plus those striking Oriental sweetlips. Keep an eye out for the clown triggerfish; they’re a bit shyer but truly gorgeous when they make an appearance. The soft tree corals and sea fans on the bommies are great for finding longnose hawkfish. This spot is generally pretty mellow, good for an easy-going morning dive when you just want to cruise and watch the reef wake up.
