Join a marine biologist off Moorea for a three-hour guided snorkel that pairs reef encounters with hands-on coral health monitoring through the Reva Atea participatory science program. Small groups make this an intimate, educational marine experience.

The boat slips from Moorea’s lagoon as sunlight skates across shallow coral gardens; a marine biologist points out a living map of branching and boulder corals while the hull hums beneath you. In three hours you’ll move from observation to action: fitting a mask, learning simple survey methods, and recording coral health with the Reva Atea community.

Wildlife
History
Moorea formed as a volcanic island within the Society Islands; its reefs and bays have long supported Polynesian fishing and navigation practices.
Conservation
Coral bleaching and human impacts threaten reefs here—participatory monitoring helps track recovery, and operators encourage non-contact snorkeling and reef-safe products.
Reserve your spot on the Reef Exploration with Reva Atea participatory science today and enjoy a trusted, highly rated experience designed to help you make the most of your adventure.
Go early for clearer water
Morning departures often have calmer seas and better visibility for identifying coral species and completing surveys.
Bring a personal mask if you have one
Snorkel gear is provided, but a well-fitting personal mask prevents leaks and fogging during surveys.
Use reef-safe sunscreen
Protect your skin and the reef—choose mineral-based sunscreen and apply before boarding to reduce chemical runoff.
Stay within the small-group plan
Limited to six guests—listen to the guide and follow survey protocols to keep data consistent and minimize reef impact.

Reduces fogging and improves fit compared with loaner masks provided by the operator
Rash guard or UV shirt
Lightweight sun protection for long periods on the water and while snorkeling
