Three Trees
Three Trees lies at the north-east corner of Ko Bangu (island 9), named after a row of trees on the shore that marks the drop point. A fringing reef of healthy hard corals runs from about 5 to 20 m, home to morays, octopus, mantis shrimps and feeding hawksbill turtles. Further out, boulders from about 22 m are covered in fans and glassfish, with leopard sharks around them and occasional Napoleon wrasse. Fewer boats visit than the neighbouring sites.
