The biggest of these islands is Ko Ha Yai, which has a series of caves and caverns for divers to explore. Most of these caverns have big entrances to allow alot of natural light to enter the caves. Most caves have stalactites hanging 30 meters above the water.
    The Emerald Cave is one good cavern to explore. During high tide, divers can swim through a large cavern underwater and emerge in a lagoon with a beach and its own jungle. The lagoon and jungle are surrounded by tall cliffs, so the cavern is the only way out. The create a wonderful experience for divers that come here.
