A “muck diver’s paradise” with it’s virgin corals and diverse macro-life. Explore the Emerald Cave – a secret lagoon and old smuggler’s den, hidden inside the island of Ko Mook.  

Don't miss the lunchtime snorkel into the Emerald Cave for a chance to experience this breathtaking natural phenomenon.  Ko Kradan offers virgin reefs, coral species and other rare and unusual species not found at other dive sites in our area. Visibility tends to be less impressive as at some of our other sites, however the sheer abundance of soft bushy corals and life packed amongst them mean that the Southern Islands are a Macro-lovers heaven. Ko Mook and Ko Wean are great places to explore and look for Seahorses, Pipefish and brightly coloured Nudibranches. Keep an eye out for pods of Cobia which can often be glimpsed around Cobia Point, as well.
