Diving Requirements

Scuba diving requires appropriate certification and medical suitability. Guests without certification can still join every snorkelling, lagoon, kayaking and reef-interpretation session, and introductory dives can be arranged with certified instructors where conditions allow.

The advanced and repeat dives on Day 28 are open to qualified divers. Tell us your certification level when you enquire and we will map the dive days to your group.
