Explore Tahanea's UNESCO-calibre coral gardens with a private marine biologist guide who turns every fin-kick into a masterclass — this atoll's reef is among the healthiest in French Polynesia and virtually untouched by human habitation.
What to expect
Boarding a nimble zodiac at the ship's gangway, your biologist-guide takes you to three micro-habitats within the lagoon: a coral bommie garden, a sea-grass manta cleaning station, and the outer slope where lemon sharks circle lazily below. She hands each guest a waterproof species identification card and narrates in real time via an underwater slate. Post-snorkel, she debriefs over fresh passion-fruit juice, sharing her own research images of the reef taken over multiple seasons.
Good to know
Maximum 6 guests ensures genuine personal attention. The guide requests reef-safe, mineral-only sunscreen — she will provide it free of charge if you forget. Allow 3.5 hours total including transfers. Tahanea's atoll has no pier; all boarding is by tender from the ship.
