About this site
First Tree is a dive site off Koh Koun, a small island in Cambodia's Krong Preah Sihanouk province, within the Gulf of Thailand near the Koh Rong archipelago. It's typically reached by boat from Sihanoukville or from operators based on Koh Rong and Koh Rong Samloem. Divers here have reported a mix of reef life including argus wrasse, bengal sergeant, pastel-green wrasse, copperband and eightband butterflyfish, along with black longspine urchin, boring giant clam, and viola land hermit crab.
