Bangoo Island, or Koh Kao, is a small island known for its uniquely shaped rock formations. The highlight for divers is the underwater structure known as Christmas Point, a large and intricately beautiful cluster of rocks that spans a wide area. Here you will find vibrant coral reefs and healthy patches of seagrass, making it a perfect habitat for a diverse array of marine life, including ribbon eels, silver-tip sharks, grouper, mudskippers, and mantis shrimp.
