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.
Verified experiences and guided adventures in the surrounding area.

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.
Moorea’s reefs formed around a volcanic island rim and have supported Polynesian fishers for centuries. The island’s bays—Opunohu and Cook’s—shape currents that feed nutrient pockets and diverse reef assemblages. Reva Atea’s participatory science builds on local knowledge and modern monitoring to track bleaching, disease, and recovery across these underwater gardens.
Expect close encounters with colorful reef fish, occasional green sea turtles, and the quiet architecture of corals in many shapes. The small-group format (max six) keeps the experience personal and hands-off: you’ll learn transect methods, spot indicator species, and log data that researchers can use.
Practical guidance: arrive hydrated and sun-protected; snorkel gear is provided, but bring a well-fitting mask if you prefer your own. This activity suits most swimmers—no advanced skills required—but practice breathing through a snorkel beforehand. Morning departures usually mean calmer water and better visibility; avoid reef contact and use reef-safe sunscreen. The operator supplies bottled water and juice and asks guests to confirm details at booking. If weather cancels, the provider’s policy allows refunds for cancellations made at least 24 hours prior.
This trip balances discovery and stewardship—appropriate for travelers who want to see Moorea’s reefs and leave them healthier than they found them.
easy.
3 hours.
Suitable for most swimmers and people in average physical condition; brief swims and surface snorkeling required
No advanced skills are required—guides brief basic snorkeling and safety procedures; some comfort in the water is recommended.
Families may join, but confirm age and snorkeling ability with the operator when booking to ensure safety and appropriate equipment.
Yes—mask, snorkel, and fins are provided, along with bottled water and soft drinks; bringing your own mask is recommended if you prefer one fit.
Trips may be canceled for safety; refunds are available if you cancel at least 24 hours before departure or if the operator cancels due to weather.
Moorea formed as a volcanic island within the Society Islands; its reefs and bays have long supported Polynesian fishing and navigation practices.
Coral bleaching and human impacts threaten reefs here—participatory monitoring helps track recovery, and operators encourage non-contact snorkeling and reef-safe products.
Koaboattour operates guided outdoor trips and adventures with an emphasis on safety, stewardship, and memorable experiences.
