Italy’s appeal for divers often gets overshadowed by its pasta and ancient ruins, but that’s a mistake. We find the diving here to be distinctly Mediterranean - less about flamboyant coral and more about intriguing rock formations, historical relics, and the thrill of encountering larger pelagics in surprising places. Head south to Campania for submerged Roman cities near Naples, where history really does come alive underwater. Or, if the big stuff is your draw, Sardinia often delivers with barracuda schools and even dolphins, particularly around its offshore islands. Our best dives have always been in the marine protected areas like Ustica, where the local blackfish and corb are noticeably bolder, or the dramatic walls of Portofino, best explored during the shoulder seasons when the summer crowds thin out.

Naples & Campania

Diving in Naples and Campania? We’re talking about more than just a dip. You’re literally swimming through history here, especially at the Baia Underwater Archaeological Park. Seeing those ancient Roman villas and mosaic floors, now home to darting damsel fish and curious brown combers, it’s genuinely surreal. Beyond Baia, the volcanic coastline is a gift to divers. Think dramatic drop-offs, caves that beg exploration, and arches draped in vibrant Devonshire cup coral. We love seeking out the more unusual creatures here, like the Rufus snake eel slithering in the sand or the surprisingly charming odd bobtail squid. Visibility can vary, but on a good day, the light filtering through the arches is incredible. The wrecks are a particular highlight for us, often encrusted with bottleneck sea cucumbers and patrolled by conger eels. We’d suggest visiting in late spring or early autumn; the water is warm, and the summer crowds have thinned out, making for a much more peaceful experience. Just be ready for some boat traffic, it’s a busy bay.

Portofino & Liguria

The Italian Riviera might conjure images of pastel villages and yacht-dotted harbours, but drop beneath the surface at Portofino and Liguria, and you’ll find some seriously compelling diving. We love the dramatic topography here - sheer walls draped in red gorgonian fans, secret caves, and pinnacles that scrape the surface. Keep an eye out for curious painted combers zipping through the crevices and we've even spotted loggerhead turtles cruising by on occasion. This is quintessential Mediterranean diving, where the magic lies in the details and the feeling of exploring ancient underwater landscapes. Our favourite time to visit is late spring or early autumn. You dodge the biggest crowds, and the water still holds a pleasant warmth. We’d suggest focusing on the Portofino Marine Protected Area for the best chance of encountering healthy gorgonian forests and schools of blacktail bream. The wrecks are a real highlight too; they've become artificial reefs, providing shelter for scorpionfish and morays. Currents can pick up, particularly around the exposed pinnacles, so it’s always worth chatting with the local dive centres about conditions on the day.

Sardinia

Sardinia is a firm favourite of ours in the Mediterranean. We particularly love the island's west coast around Alghero, where the limestone cliffs drop dramatically into the sea, hiding a maze of grottoes and caverns just begging to be explored. Drop into Neptune's Grotto for a surface interval - it’s touristy, sure, but incredible - then head out for a dive in the Cala del Lazzaretto. We’ve finned through schools of salema here so thick they genuinely blot out the sun, a shimmering wall of silver. The marine reserves, like Tavolara Punta Coda Cavallo, offer some of the healthiest reefs we’ve seen in the Med. Look closely in the seagrass beds for broadnosed pipefish, and keep an eye out for flashes of black coral on deeper walls. Wrecks are scattered around too, often draped in fishing nets, home to resident pandora and pearl-sides. Visibility is usually superb, often pushing 30 metres, especially in late spring when the water starts to warm up but the summer crowds haven’t fully arrived. Currents can pick up, particularly around the capes, so it’s worth checking the local conditions.

Ustica

Ustica holds a special place in our hearts; it was Italy's first marine protected area for good reason. Diving here feels like stepping back to a healthier Mediterranean. We love the intricate cave systems and the pinnacles that rise from the deep, often draped in Neptune's lace. You'll regularly spot schools of horse mackerel flashing past, and if you’re lucky, a curious Odd Bobtail Squid tucked into a crevice. The dive sites are a mix, from beginner-friendly reefs to more adventurous pinnacles, but it’s the sense of protection that really stands out. Visibility is generally excellent, often pushing 30 metres in summer, making the light rays in the grottos particularly dramatic. Our favourite site is the Grotta dei Gamberi, a shallow cave packed with red shrimp - look closely for them clustered on the roof. For something deeper, the Secchitello pinnacle is a real magnet for pelagics, especially in late summer when the water is warm and the baitfish are thick. We'd suggest visiting in early autumn; the crowds thin out, but the water is still bathtub warm, and the marine life remains active. Keep an eye out for Cuvier's Beaked Whales, though they’re shy, they do pass through these waters.
