Shallow Saint-Leu reef with two lava arches and clear water.
Deux Arches is a shallow Saint-Leu reef site built around two lava-flow arches inside the coral reef. The dive stays simple and route-light, with the arches and surrounding reef giving you most of the interest. Expect clear water and a strong mix of reef life, plus a profile that suits new divers and relaxed boat dives. Even so, current can be moderate, so it pays to keep the plan controlled.

Community notes to help plan your visit.
Scuba Diving
A shallow-to-moderate dive with arch swim-throughs around 5 m and 9 m.
Freediving
Shallow enough for trained freedivers in calm conditions, but it is best treated as a controlled, short session rather than a long traverse.
Snorkeling
Snorkeling is possible on calm days because the arches sit shallow in clear water. The best sessions stay near the reef top and avoid stronger current.
