Les Arches

Light falls through crevices into a cave beyond a stone arch

A descent through a stone arch into a large cave where shafts of daylight fall through cracks in the rock. Beyond the caves the route reaches the foot of a drop-off at 40 m, so the dive, which spans 6 to 40 m, is kept for divers with a good level of experience.

Also known as The Arches, Arches.

The dive

Divers drop from 6 m to 30 m and reach a stone arch, then swim beneath it. On the far side the route enters a large cave lit by rays of light that come in through crevices in the rock. A second cave opens off the first, home to hatchetfish and goatfish.

Leaving the caves at 40 m, divers come out at the foot of a drop-off and follow it to a rock porch. On the way back to the boat, two more arches stand at 30 m.
