Caye Bertrand

Also known as the Arch of Aeolus

Town : Case-Pilote

An isolated coral mass in clear water — The mass, alone in the blue.

Caye Bertrand goes by a second name, the Arch of Aeolus. We dive it from Case-Pilote, often in the same outing as Neptune’s Garden.

What a “caye” is

In the Caribbean, a caye is a rocky or coral shoal rising from the bottom without breaking the surface. It is neither an island nor a fringing reef: it is an isolated mass, surrounded by deeper water.

The word comes up often among our sites, and it always announces the same thing: a lone relief in open blue, and therefore a concentration of life.

An arch, and how to go through it

The site’s second name says what is there. An underwater arch is a natural passage cut through rock, open at both ends.

You go through slowly, without hard finning: the wash from a sharp kick lifts sediment off the ceiling and ruins visibility for those behind. Under an arch, the courteous diver goes gently.
