Diving Calvi: B-17 wreck and rocky cliffs

Calvi is a premier Mediterranean destination for divers seeking a mix of historic wreck diving and dramatic underwater topography. Based around the Calvi marina, the area offers everything from shallow reef exploration to deeper wreck encounters. It serves as an ideal hub for those wanting to explore the outskirts of the Scandola nature reserve, where the biological richness is exceptional due to strict protection, providing a diverse underwater landscape within a very short boat ride from the town.

Diving here is dominated by short boat excursions departing directly from the marina. The underwater terrain is varied, ranging from sandy plains to steep rocky drop-offs and underwater ridges. The B-17 wreck sits between 25 and 28 meters on a sandy bottom at the foot of the citadel, while the Revellata peninsula offers more complex rocky structures. Currents are generally light, making it comfortable for most, though visibility can be affected by wind and seasonal swells. It is a classic Mediterranean setup: clear water, sun-drenched reefs, and a mix of wreck and natural formations.

The Mediterranean fauna here is classic but reliable. Between May and September, you can spot brown groupers and Mediterranean barracudas patrolling the rocky edges. The proximity to the Scandola reserve ensures high biodiversity, particularly around the edges like Punta Rossa or Punta Muchillina, where the protected status of the neighboring reserve helps maintain a healthy ecosystem for various Mediterranean fish species.

The best period for diving is from May to September, when the sea is calmest and visibility is at its peak. During these months, the tourist season is in full swing, providing a complete range of boat services. Diving in late spring or early autumn offers a quieter experience with fewer boats on the water, though visibility may be slightly less consistent than in mid-summer.

The sites are accessible to most levels, but depth and terrain dictate the best approach. While beginners can enjoy shallow reef sites, the B-17 wreck requires an Advanced level or PE40 certification due to its depth and the need for careful decompression management. Nitrox is highly recommended to maximize bottom time if you plan to dive multiple times a day.

Getting to Calvi depends on your starting point in Europe. Most travelers from London, Manchester, or other major hubs fly into Calvi Sainte-Catherine (CLY), often via connections in Paris or Nice. For those bringing heavy gear, taking a ferry from Italy—such as Genoa or Savona to Bastia—is a common and practical option, allowing you to continue to Calvi by road or rail. Once in town, most dive boats depart directly from the Calvi marina, which is easily accessible by foot or local transport from town-center accommodation.

If you are aiming for the B-17, try to book an early morning slot to avoid the crowds at the mooring and take advantage of the best light. Because the wreck sits at 25-28 meters, ensure your certification and buoyancy skills are sharp. To get the most out of your trip, don't just stick to the wreck; the rocky ridges of the Revellata and the outcrops of Algajola or Spano offer completely different environments. Be aware that scuba diving is strictly prohibited inside the Scandola reserve; all your dives will take place on its perimeter, where the biological richness is high precisely because the core is protected. Avoid planning a tight itinerary during peak summer if you are relying on seasonal ferry schedules, as delays can eat into your dive time.

A stay of 5 to 7 days is ideal. This allows enough time to explore the B-17 under good conditions, visit the Revellata cliffs, and include a day for a boat excursion to view the Scandola cliffs from the surface, which is a must-do even if you aren't diving inside the reserve.
