Italy isn't just beautiful above ground, it’s stunning below the surface too. For divers, both beginners and seasoned pros, the country offers an unforgettable blend of crystal-clear waters, ancient history, and thriving marine life. 

From sunken Roman villas to mysterious wartime shipwrecks, diving in Italy is like stepping into a time machine, just underwater. Whether you're new to scuba or looking for your next deep challenge, this guide will help you explore Italy’s top submerged archaeological sites and marine parks.

Italy is welcoming to newcomers to diving. Many of its best underwater treasures lie in calm, shallow waters - ideal for your first underwater experience or a relaxed exploration.

Imagine gliding over ancient Roman ruins, columns, statues, and marble floors, just a few meters underwater. That’s Baiae. Once the Roman Empire’s answer to the French Riviera, Baiae was a glamorous spa town for emperors, generals, and aristocrats. Over time, volcanic activity slowly sank this opulent playground beneath the sea, leaving behind a hauntingly beautiful archaeological park you can explore by diving.

You won’t find another place like this in the world. The Underwater Archaeological Park of Baiae offers a one-of-a-kind opportunity to swim through a sunken city, complete with paved roads, mosaic courtyards, and life-sized statues still standing where they once welcomed guests 2,000 years ago. It's like diving into a museum, only without the glass cases.

What to Look For Underwater:

• The Nymphaeum of Emperor Claudius: a ceremonial fountain chamber with replica statues (the originals are in the nearby museum)
• Thermal baths, stone benches, and remnants of wealthy villas
• Mosaics and marble floors, remarkably preserved.

Occasional bubbling sea vents, a reminder that the volcano that sank Baiae is still very much alive.

Baiae is an ideal site for beginner divers or even snorkelers. The ruins rest in calm, shallow waters (5–8 meters) with excellent visibility. Dive operators here are experienced with newcomers and often offer Try Scuba sessions - no certification required. And for Experienced Divers? Even if you’re already certified or have plenty of dives under your belt, Baiae is still a bucket-list site. The thrill of diving through history, tracing outlines of submerged buildings, and encountering entire ancient villas is an experience you can’t replicate anywhere else.

If Baiae is your main goal, Pozzuoli is your best base. It’s the heart of the Campi Flegrei area and just minutes from the dive sites. You’ll find charming local hotels and B&Bs, great seafood restaurants, and a lively marina. Looking for something more iconic? Naples is only a 30-minute drive away. Stay near the Historic Center or Chiaia district for easy access to both culture and coastal views.

Hidden beneath the waves of a quiet cove near Portofino, the Christ of the Abyss (Cristo degli Abissi) is one of Italy’s most emotionally powerful underwater experiences. This bronze statue of Jesus Christ stands with arms outstretched in a gesture of peace, resting 15 meters below the surface in the Bay of San Fruttuoso. Created in 1954 to honor divers and those lost at sea, it’s become a beloved dive site for locals and travelers alike.

More than just a dive, this is a spiritual encounter with art and nature combined. The statue rises from the seabed like a guardian of the Mediterranean, surrounded by gentle currents, soft coral growth, and fish darting between rocky outcrops. It’s accessible, calm, and photogenic - making it one of Italy’s most beginner-friendly yet meaningful dives.

What to Look For Underwater:

• The statue itself, patinated by decades underwater
• Sea bream, groupers, and small colorful wrasse that often circle the area
• Sunlight rays filtering through the water, giving the scene an ethereal glow

This dive is a favorite for first-time certified divers, thanks to its manageable depth and conditions. Snorkelers can also spot the statue from above, making it a great option for families or groups with mixed experience levels. Still, even seasoned divers find themselves deeply moved by the atmosphere.

The best base is Santa Margherita Ligure, a relaxed seaside town just a short boat ride from San Fruttuoso. It offers charming hotels, beach promenades, and easy train access. Nearby Portofino is more upscale, ideal for a luxury stay with fine dining and boutique shopping.

When you’re not diving, explore the trails of Portofino Natural Park, visit the secluded Abbey of San Fruttuoso tucked into the cliffs, or hop on a ferry to Camogli, a colorful fishing village with excellent seafood. For a longer stay, consider extending your trip to the Cinque Terre, just down the coast, for dramatic views and coastal hikes. We recommend starting from this tour and then adding your diving experiences if interested!

Off the northeastern coast of Sardinia, the Maddalena Archipelago is a protected marine paradise made up of rugged granite islands and crystal-clear waters. This national park is a favorite for beginner divers thanks to its calm conditions and vibrant underwater scenery. Dives here are relaxed, scenic, and rich with life - perfect for a first real taste of the Mediterranean Sea.

The shallow reefs around Caprera and Spargi islands are full of color and movement, with sandy bottoms, rocky canyons, and quiet coves teeming with marine life. The area’s protection means it’s bursting with biodiversity and ideal for slow, easygoing dives where you can take it all in without rushing or worrying about currents.

What to Look For Underwater:

• Curious octopus hiding in rock crevices
• Starfish, sea urchins, and vibrant wrasse swimming along the reefs
• Bright sandy patches perfect for learning buoyancy and control

Maddalena’s dive spots are perfect for Try Scuba dives or beginner certifications. Even experienced divers enjoy them for their peaceful beauty and excellent photo conditions.

Palau is the main gateway to the archipelago and a great spot for cozy hotels and dive schools. You can also stay on La Maddalena island itself for a more laid-back, car-free experience. Between dives, rent a boat to explore hidden beaches, hike on nearby Caprera Island, or simply enjoy the seafood in town. For longer stays, combine your dive days with inland trips to Costa Smeralda or Nuraghe ruins for a taste of Sardinia’s culture and history.

Just off Sicily’s western coast, the Egadi Islands are a peaceful escape into clear waters and coastal charm. Favignana, the largest island in the group, is a haven for beginner divers and snorkelers thanks to its sheltered bays, sandy bottoms, and thriving marine reserve. It’s a spot where nature, tradition, and simplicity meet in a stunning Mediterranean setting.

The waters here are part of Italy’s largest marine protected area, home to healthy reefs, fish-rich seagrass meadows, and the remains of ancient tuna traps now colonized by sea life. Diving is easy and enjoyable, with lots to see even at shallow depths, making it an ideal training ground for first-timers.

What to Look For Underwater:

• Moray eels, groupers, and sea bass cruising between rocky ledges
• Stingrays and octopus hiding in the sand
• Peaceful shallows perfect for long, relaxing dives or snorkels

With clear visibility and mild conditions, the Egadis are perfect for half-day dive outings or full certifications. They're also a great base for combining sea adventure with slow island life.

Stay in Favignana town, where bikes are the main form of transport and everything moves at a gentle pace. The island has small inns, fresh seafood trattorias, and easy boat access to dive sites. Beyond the water, visit the old Tonnara museum, ride to Cala Rossa for dramatic cliffs, or take a ferry to Trapani for baroque streets and sunset views over the salt pans. For a bit of elevation, don’t miss the cable car up to Erice, one of Sicily’s most scenic hill towns. For some inspo, check out some of our best Sicily itineraries - fully customizable.

Floating quietly in the Tyrrhenian Sea between Rome and Naples, the islands of Ventotene and Santo Stefano are an off-the-radar diving destination ideal for certified, confident divers. Once part of the Roman Empire’s prison system, today these tiny volcanic islands are surrounded by a protected marine reserve where underwater history and geology collide.

Ventotene’s seabed holds the remains of Roman cargo ships, their amphorae still clustered together as they were when the vessels sank nearly 2,000 years ago. These dives go deep, often 35 to 40 meters, making them exclusive to experienced divers. You’ll also find modern wrecks, dramatic volcanic rock formations, and lively reef walls. The isolation of the site means low diver traffic, great visibility, and a peaceful atmosphere for focused exploration.

What to Look For Underwater:

• Ancient amphora fields from Roman merchant ships
• Steep rock faces and reef walls covered in sponges and sea fans
• Lobsters, amberjacks, and groupers in deeper crevices

The marine reserve enforces strict protections, so marine life thrives here. These are not training dives - they’re for those comfortable with depth, currents, and technical skills.

Ventotene is small, rustic, and refreshingly untouched by mass tourism. Stay in a local guesthouse near the port and enjoy a slow-paced routine of diving, walking, and seafood dinners. On land, explore the Roman harbor still in use today, the Villa Giulia ruins, or the prison island of Santo Stefano, which offers guided tours and sweeping sea views. For a longer journey, pair Ventotene with time in Gaeta or Sperlonga, both charming mainland coastal towns within reach by ferry.

Set beneath the towering limestone cliffs of Capo Caccia, near Alghero in northwestern Sardinia, Nereo Cave is the Mediterranean’s largest sea cave and a magnet for advanced divers. With its twisting tunnels, natural arches, and otherworldly air pockets, this dive feels like entering a submerged cathedral sculpted by nature.

Spanning over 300 meters, the cave system is layered with passageways at varying depths, with the deepest parts reaching 33 meters. The cave walls are cloaked in red coral, sponges, and gorgonians, while the entrance often hosts groupers, lobsters, and moray eels. Light beams filtering through openings create an eerie beauty that's both thrilling and serene - ideal for experienced divers with a sense of adventure.

What to Look For Underwater:

• Natural windows and arches lit by shimmering blue light
• Dense red coral colonies and rare sponges
• Hidden marine life in crevices: scorpionfish, slipper lobsters, and octopus

Because of the overhead environment and varying visibility, this dive is best for those with cave or deep diving experience. Good buoyancy control and comfort in enclosed spaces are essential.

Stay in Alghero, a historic Catalan-style town with seaside charm and direct access to Capo Caccia. Dive boats leave daily from the harbor. Outside the water, visit Neptune’s Grotto, a walk-in coastal cave with stunning rock formations, or stroll Alghero’s old town for lively markets, gelato stops, and romantic sunset views over the city walls.

The island of Elba, famous for its connection to Napoleon, is also one of Italy’s premier diving destinations - especially for wreck enthusiasts. This island in the Tuscan Archipelago boasts a mix of shallow and deep dives, including historic shipwrecks and ancient Roman ruins scattered across the seafloor.

Elba’s dive sites range from beginner-friendly to technically challenging. The Elviscot, a small cargo ship that sank in the 1970s, lies at just 12 meters and is perfect for photographers and relaxed exploration. For advanced divers, the Santa Rita wreck sits at 46 meters, offering a haunting descent into history. Other dives include Roman cargo wrecks near Procchio and Capo Enfola, revealing amphorae and trade goods from centuries past.

What to Look For Underwater:

• The Elviscot wreck: intact, easy to navigate, and covered in marine life
• Deep wrecks with rich backstories and advanced navigation routes
• Roman-era amphorae embedded in rock beds

The combination of clear water, archaeological interest, and wreck diversity makes Elba a rich site for experienced divers looking to blend history with adventure.

Stay in Marciana Marina or Portoferraio, both well-equipped with dive centers and seaside charm. Outside diving, explore Napoleon’s villa, hike in Elba’s National Park, or take a cable car to Monte Capanne for panoramic views of the archipelago. Ferries to and from the Tuscan coast make it an easy island escape. Would you like to make this trip a reality? Then just send us a quick whatsapp text and let’s spark the conversation.

Sardinia’s southern coastline hides several deep, haunting wrecks from World War II, ideal for expert divers seeking powerful, immersive dives. Among the most notable is the Entella, an Italian freighter sunk in 1943 near Capo Spartivento, now resting at depths of around 40 meters.

The combination of historical wrecks, volcanic seabeds, and strong marine currents creates a dramatic setting beneath the waves. These are dives that challenge your training and reward your curiosity. Many wrecks remain remarkably intact, with visible holds, metal structures, and marine life reclaiming the space.

What to Look For Underwater:

• The Entella wreck, with structural remains and resident groupers
• WWII debris fields with scattered machinery and artifacts
• Barracuda, amberjack, and rays cruising around the site

Due to depth and limited accessibility, these dives require advanced certification, excellent buoyancy control, and often tech diving gear. They're best for experienced wreck divers or those completing deep dive specializations.

Cagliari, the capital of Sardinia, is your ideal base - offering dive centers, equipment rentals, and guided tours to these remote sites. After diving, explore the historic Castello district, unwind at Poetto Beach, or visit the Roman Amphitheater in town. For a quieter option, nearby Pula provides easy coastal charm and access to Nora, an ancient city partly submerged by the sea.

Off Sicily’s northwest coast, the tiny island of Levanzo in the Egadi archipelago hides one of Italy’s most fascinating archaeological dive sites: the Cala Minnola Roman shipwreck. At around 27 meters deep, this well-preserved wreck tells the story of ancient maritime trade and offers a quiet, remote dive setting for seasoned explorers.

This Roman wreck site is remarkable not just for its age but for its context. Dozens of amphorae still lie clustered on the seabed, giving divers a real sense of how goods were transported across the Mediterranean nearly two thousand years ago. The protected area keeps boat traffic low and marine life healthy.

What to Look For Underwater:

• Roman amphorae from the 1st century BCE
• Flat, sandy bottom with sponges and coral surrounding the wreck
• Damselfish and sea bream weaving through ancient cargo

Though the site isn’t especially deep by expert standards, its archaeological value and remote location make it a unique experience best suited for confident divers.

Stay in Favignana and take a short boat ride to Levanzo for your dive. On Levanzo itself, you’ll find quiet trails and the Grotta del Genovese, a cave with Neolithic rock carvings. Pair your dive day with a relaxing lunch at the harbor or a sunset ferry ride back to Trapani, where baroque architecture and Sicilian street food round out the experience. We would love to plan this for you, let’s talk about it!

• Plan your dive season wisely

The best time to dive in Italy is from May to October, when the water is warm, the visibility is clear, and marine life is at its most active. Whether you're heading into sea caves or floating above Roman ruins, summer and early fall offer the smoothest and most scenic conditions.

• Know your limits and your licenses

A basic Open Water certification is perfect for many of Italy’s top sites, especially those with reefs and shallow ruins. But for deeper wrecks, caves, and archaeological dives, you’ll need an Advanced Open Water or technical certification. It’s worth the extra training for access to Italy’s more exclusive underwater experiences.

• Book a local guide, it’s worth it

Many sites like Baiae and Cala Minnola require diving with a licensed guide, not just for safety but for the stories. These experts turn a beautiful dive into a living lesson in Roman history, WWII events, or volcanic geology.

• Respect the ruins and marine life

Italy’s underwater sites are protected by law. Never touch, move, or remove any artifacts or marine creatures. It’s illegal and more importantly, it helps preserve the magic of these places for future generations.
