Why dive here
With 158+ marine species recorded in the area - including blacktip reef sharks, blue-spotted stingrays, mobula rays (devil rays), whale sharks and pufferfish - Bio Rock offers some of Gulf of Thailand's richest reef diving. Water sits around 28°C.
Bio Rock sits at a comfortable 14 meters, making it an easy drift for newer divers. The site is a mix of natural rock formations and artificial structures, slowly growing a new coral community. We often spot juvenile reef fish taking shelter, along with the occasional moray eel peeking from the rocks. It’s a gentle introduction to Gulf of Thailand diving, especially if you’re looking for calm conditions.
