Le Fer à Cheval is a guided coral-tunnel dive in Tahiti Iti.
Guided Tahiti Iti outings run when conditions allow; plan it as a booked boat dive, not a casual solo stop.
Le Fer à Cheval is a horseshoe-shaped coral tunnel on the Tahiti Iti side of Tahiti, where a lagoon passage opens to the ocean. The site rewards steady buoyancy and calm-day planning: the lagoon approach is the easiest part, the tunnel is the signature feature, and the ocean side is known for resting whitetip reef sharks, eels, and pipefish. Treat it as a guided outing rather than a casual shore stop.

Depth range, seasonality, and planning context.
Best Season
Year-round when seas are settled.
Typical Conditions
Calm lagoon water on the approach, then more movement at the tunnel mouth and ocean side when the sea builds.
Hazards, restrictions, and access requirements.
Key Hazards
Safety Notes
The tunnel creates an overhead section, so buoyancy matters; keep a conservative line through coral edges and watch the ocean-side exit.
Access Restrictions
Do not assume the site is runnable every day; plan around local operator scheduling, sea state, and the tunnel's overhead section.
Legal Notes
Follow the day's briefing and local access limits; treat the site as a condition-sensitive guided excursion rather than an open shoreline stop.
Community notes to help plan your visit.
Scuba Diving
Best as a guided scuba dive for certified divers comfortable with an overhead coral passage and careful buoyancy.
Freediving
Freediving is not the main use case here; the tunnel and operator-led access make scuba the cleaner fit.
Snorkeling
Snorkelling is secondary here; the site is more about the tunnel and ocean-side wildlife than a long surface swim.
