The harbour at Saint-Pierre holds what divers routinely rank among the best wreck diving in the world. At least ten ships sank on 8 May 1902, mostly in the 30–50 metre depth range, and they have remained essentially undisturbed since then. Hulls, masts, anchors, and cargo are all intact, and decades of undisturbed growth have turned the wrecks into dense artificial reefs — coral, sponges, and schools of tropical fish cover every surface.
The most accessible wrecks — the Gabrielle (at 15m) and the Tamaya (at 18m) — are within range of open-water certified divers. The Roraima, a Canadian merchant vessel, sits deeper and is better suited to experienced divers; photographs taken after the disaster show her superstructure above water, but she settled to her current position over the following days. Several dive centres in town offer guided wreck dives with equipment rental, and the dives are generally well-supervised with good visibility when the sea is calm. If you dive at all, this is the reason to come to Saint-Pierre. The combination of intact ships, clear Caribbean water, and the knowledge of what put them there makes for an experience unlike any other wreck dive.
