Sardinia, located in the heart of the Mediterranean Sea, is one of Italy’s premier scuba diving destinations. Known for its crystal-clear waters, dramatic coastline, and well-preserved marine environments, Sardinia offers diverse diving experiences suitable for both beginners and experienced divers. The island’s combination of rocky reefs, underwater caves, walls, and shipwrecks makes it a highly versatile destination for underwater exploration.

Marine Life

Sardinia’s marine life reflects the richness of the Mediterranean ecosystem. Divers can expect to see large schools of seabream, barracudas, groupers, wrasse, and amberjacks. Octopuses, moray eels, cuttlefish, and lobsters are commonly found hiding among rocks and crevices. In protected areas, sightings of eagle rays and sea turtles are increasingly common.

Macro life is also abundant, with nudibranchs, shrimp, crabs, and colorful sponges found throughout many dive sites. Thanks to marine reserves and strict fishing regulations in certain areas, biodiversity remains healthy and visually impressive.

Best Dive Spots for Experienced Divers

Tavolara–Punta Coda Cavallo Marine Protected Area is one of Sardinia’s top dive regions. Featuring deep walls, caves, and strong currents, it attracts experienced divers looking for dramatic scenery and large marine life.

Grotta di Nereo near Alghero is one of the largest underwater cave systems in the Mediterranean. With multiple entrances, tunnels, and chambers, it offers an advanced cave-diving experience with excellent visibility.

The wreck of the KT12 near Capo Carbonara is a popular advanced dive, resting at greater depth and attracting schools of fish and encrusting marine life.

Sardinia offers a long diving season that typically runs from April to November. The best conditions are usually found between June and September, when sea conditions are calm, visibility is excellent, and water temperatures are at their warmest.

Water temperatures range from approximately 59°F to 64°F in spring, rising to 73°F to 79°F during the summer months. Visibility often exceeds 80 feet, especially during the peak summer season. Currents are generally mild, although they can be stronger around headlands and marine reserves.

Open Water Diver certification courses usually range from $400 to $550 USD and include instruction, equipment use, and certification fees. Many dive centers offer discounted multi-dive packages, making Sardinia a cost-effective option for divers planning several days of diving.
