Limestone canyons, granite islands, and giant grouper in Corsica's protected far south
Southern Corsica requires disciplined boat and reserve behavior. Exposed strait weather, current around shoals, summer traffic, rocky terrain, and the distance to hyperbaric care are the main planning issues. Dive with a licensed local center, accept site substitutions, stay within training and recent experience, and keep an oxygen-and-emergency plan in every briefing.
Conservation is operational, not decorative. Zoning determines where diving, fishing, anchoring, landing, and walking are legal. Posidonia, gorgonians, grouper, seabirds, historic material, and island vegetation should be observed without contact or disturbance.
Confirm certification recognition, medical paperwork, recent experience, maximum planned depth, gas, reserve, ascent procedure, lost-buddy procedure, and SMB protocol before boarding. The route may involve current, surge, chop, rock passages, or a blue-water ascent. Beginners should not be placed on Merouville or exposed advanced routes simply because the sea looks clear.
For suspected decompression illness, give the highest practical concentration of oxygen, keep the diver resting and hydrated only if fully alert and able to swallow, call 15 or 112, and contact DAN Europe. Do not descend again, place the diver at altitude, or drive independently toward Ajaccio without emergency coordination. Follow conservative post-dive flying and altitude guidance from the diver's training agency, computer, operator, and DAN.
Bonifacio and Porto-Vecchio have local medical services, but the island's hyperbaric medicine service is at the Centre Hospitalier d'Ajaccio. Its location makes early recognition, onboard oxygen, and emergency-service coordination essential. The hospital publishes a hyperbaric secretariat number for service information; immediate dive emergencies should enter through 15 or 112 rather than waiting for office hours.
Travelers eligible for an EHIC or GHIC should carry it, but public-health entitlement does not replace dive-accident, evacuation, repatriation, cancellation, or private-care insurance. Disclose relevant medical history honestly on the operator's form and obtain physician clearance when required.
Wind, current, and site substitutions
The Strait of Bonifacio can develop strong wind, current, chop, and ferry-influenced surface conditions. Accept the skipper's route change or cancellation. A sheltered replacement is not a lesser safety decision.
Integral no-take zones are not normal dive sites
The reserve decree subjects scuba in integral no-take zones to individual authorization. Do not enter based on a generic map or an old online description. Use a licensed local operator and treat access as closed unless explicitly confirmed.
Boat traffic and surfacing risk
Excursion boats, ferries, dive boats, and private craft share the coast. Follow the local flag and SMB procedure, stay with the group, listen for engines, and never surface inside a marked navigation channel.
Rock, surge, and overhead-like passages
Some sites include arches, narrow rock corridors, or caves. Enter only routes appropriate to training and conditions, maintain neutral buoyancy, and preserve a direct open-water exit unless specifically qualified for another environment.
The reserve protects Posidonia meadows, coralligenous habitat, island ecosystems, fish, marine mammals, and cultural heritage. Do not touch or feed grouper, handle nudibranchs, rest on gorgonians, collect shells, remove amphora fragments, or take minerals or fossils. Maintain buoyancy above the bottom and secure gauges and cameras.
Private boaters must use legal anchoring or mooring arrangements and never drop an anchor into Posidonia. Enhanced-protection zones prohibit spearfishing. Integral no-take zones prohibit extraction and require individual authorization for scuba. On Lavezzi and other protected land, use designated landing places, beaches, and marked trails, and never camp or bivouac.
