Boat-access Tahiti Iti cave with macro life and bioluminescence.
Boat-access Tahiti Iti cave with macro life and bioluminescence.
La Grotte du Pari is a boat-access lava-tube cave on Tahiti Iti, built for guided exploration rather than open-water cruising. The tunnel is known for its macro life and bioluminescent fish, with a long overhead passage that rewards calm buoyancy, slow photography, and a careful exit line. It suits divers who want a sheltered cave-style dive with a strong focus on structure and small life rather than current or big-water conditions.
Site Conditions
Safety Notes
Treat it as a cave/overhead site: stay with the guide, keep buoyancy steady, and preserve the exit line.

Legal Notes
Follow local guide and cave-dive rules for Tahiti Iti.

Scuba Diving
Cave/tunnel environment in a lava tube with a wide passageway and marine life concentrated along the bottom.
Freediving
Freediving is not the main use case; the overhead tunnel is better handled as guided scuba.
Snorkeling
Snorkeling is not the focus; the interesting zone is inside the cave rather than at the surface.
