Dive Site Overview

Exploring La Vacca Sud reveals a complex underwater landscape. Divers navigate a terrain rich with distinct rocky structures, including two prominent flat-headed ascents that shape the site's unique profile.

Venturing deeper, extensions of the Vacca rock unveil arc-shaped formations and impressive natural arches. These create intriguing swim-throughs and offer sheltered areas, often teeming with smaller marine life seeking refuge. Multiple depth profiles exist across available routes, generally ranging from 3 m / 10 ft along the shallower reef plateaus to 30 m / 100 ft around its base.

For those seeking greater depths, specific sections like the "Danger de la Vacca" descend further, reaching up to 40 m / 130 ft and presenting opportunities for technical or experienced divers. As part of the Cerbical Islands reserve, this area consistently shows rich biodiversity within its vibrant ecosystem.

Conditions frequently present as calm, benefitting from natural protection against stronger winds and currents, which contributes to more predictable and enjoyable dives. Accessing this dive spot usually involves a brief 15-minute boat ride from the Porto-Vecchio marina.
