CharacterReef dive

StandoutExceptional marine biodiversity

Tachai Reef in the Similans gives divers a chance to explore a sprawling coral network. We often find schooling fusiliers here, sometimes so dense they dim the light. It's a relaxed dive, good for those wanting to take their time over the reef, rather than chasing pelagics.
