Boat-access arch dive in Saint-Leu, Réunion.
A local Saint-Leu operator is the practical default for access and route planning.
L’Arche de Noël is a boat-access arch dive in Saint-Leu’s marine reserve, built around a basalt formation with peaks, plateaux, and a small tunnel beyond the main arch. It suits experienced divers who want a relief-heavy profile with coral-fish life, sponges, and a route that stays interesting when you slow the pace and keep the trim tidy.

Scuba Diving
A boat dive through a basalt arch with peaks, plateaux, and a small tunnel, best handled with careful buoyancy and a guided route.
Freediving
Not a freedive-first objective. The arch and tunnel make it a scuba dive for experienced teams.
Snorkeling
Snorkeling is only a side option on calm days near the boat; the arch itself is a scuba objective.
