The Mediterranean Sea is famous for its width of historical contribution, its extremely varied marine life, and its stunning underwater landscape-things that make it a true paradise for divers. Ranging from popular dive sites such as Malta’s Blue Hole to Cyprus’s Zenobia wreck, thousands of enthusiasts are drawn to such sites every year. Still, there are many little-known treasures buried in the Mediterranean that beg for someone to come out and discover them. This article discusses some of the Mediterranean’s lesser-known diving treasures.

1. Cap de Creus, Spain

Lying on the northeastern tip of Catalonia, the Cap de Creus is a wild peninsula with as much drama above the water as below. Underwater, the scenery is riotous with color and completely smothered with gorgonians, anemones, and sponges, adorning the rocky walls. Due to its status as a marine reserve, the marine life comes in abundance and variety. Great barracudas, moray eels, and octopuses-one can even hope to see the ocean sunfish on occasion. Equally impressive is the variety in the landscape underwater: steep drop-offs, tunnels, and caves.

Must-See Locations:

• El Gat: Submarine mountain with diverse marine life and great visibility.
• La Massa d’Or: Underwater caves and tunnels in a network.

2. Ustica, Italy

Also named the “Black Pearl of the Mediterranean,” Ustica is an island located north of Sicily. It is one of Italy’s very first marine reserves but remains, for the most part, a secret known to few divers. The origin of this island is based on a volcanic eruption, hence creating an underwater world of tunnels in the lava, caves, and drop-offs. Ustica has crystal-clear waters combined with rich biodiversity in the sea, making it a good destination for all those who love adventure off the beaten track.

Best Spots:

• Grotta dei Gamberi: A cave dive known for its shoals of red shrimp, and oddly shaped rock formations.
• Secca della Colombara: An underwater plateau with big Gorgonian fans and schools of pelagic fish.

3. Kas, Turkey

Kas is a city on the southwest coast of Turkey, a place where one would experience some of the most superlative diving in the Eastern Mediterranean. Crystal-clear waters, teeming marine life, and some ancient ruins submerged beneath the waves are very positively spoken of. Kas offers dive sites no less diverse: from caves and reefs to wrecks promising great options for any level diver.

Must-See Sites:

• Canyon: Submarine canyon, but spectacular in its rock formations, including the possibility of large groupers and eagle rays.
• Lighthouse Wreck: A World War II-era wreck teeming with life and coral colors.

4. Elba Island, Italy

Elba is the largest island within the Tuscan Archipelago and one of those less known diving destinations that assure a glimpse into spectacular underwater experiences. The island is surrounded by clear waters and is richly populated by marine life, including such species as groupers, barracudas, and moray eels. Underwater landscapes on Elba are pretty varied: steep drop-offs interchange here with huge meadows of seaweed. That’s what makes this place so interesting to explore.

Must-See Sites:

• Pomonte Wreck: A well-preserved wreck of an Italian cargo ship, the Elviscot, was sitting at a depth of 12 meters and accessible to divers of all levels.
• Scoglietto di Portoferraio: A marine protected area known for its rich biodiversity and stunning underwater scenery.

5. Isola di Bergeggi, Italy

Uninhabited Isola di Bergeggi, lying offshore of the Ligurian coast, offers some of the cleanest diving in the area. The island and surrounding marine park ensure a healthy, thriving underwater ecosystem. The waters around Bergeggi are known for offering great visibility, making it just the place for underwater photography.

Must-See Sites:

• Grotta Marina di Bergeggi: Pretty sea cave with impressive stalactites and stalagmites, home to various species of marine life.
• Scoglio del Corallo: Interesting coral formations at every turn with a substantial diversity of marine life, including octopus, nudibranch, and scorpionfish.

6. Medes Islands, Spain

The Medes Islands are situated off Costa Brava. These are seven small islets that form one of the most important marine reserves in the Mediterranean. The islands are a haven for underwater life, where all types of underwater landscapes-mostly steep walls, caves, and tunnels-are to be found. They will make any diving day truly special.

Must-see sites:

• La Vaca: A dive site having a huge cavern with remarkable light effects and richness of marine species.
• El Dofí Sud: Offers outstanding underwater walls, covered in coral and gorgonians, with frequent sights of groupers and eagle rays.

7. Gozo, Malta

While Malta is famous for diving, Gozo still has some rather unknown but breathtaking sites. Dramatic drop-offs, caves, and wrecks make the underwater world of Gozo very remarkable; excellent visibility prevails around the year. The island with its rocky coast and crystal-clear waters is a great destination for more adventurous divers who are ready to explore hidden Mediterranean depths.

Must-See Sites:

• Blue Hole: This is a breathtaking natural feature, leading into a cavernous underwater cave system with possibilities for advanced divers.
• Inland Sea: Probably the most unique dive around, starting from a shallow lagoon and taking the diver through a remarkably long tunnel out to the open sea, almost as if on another world.

8. Sark, Channel Islands

Although technically in the English Channel, Sark is part of the Mediterranean ecozone and deserves a mention for having some of the best diving available. The smallest of the Channel Islands, Sark offers a selection of some of the most diverse underwater landscapes in the region. The waters around the island have plenty of marine life, and strong currents bring enough nutrition for the organisms to keep the ecosystem going.

Must-See Sites:

• Gouliot Caves: Sistema de cuevasulls flushed with colored sponges, sea anemones, and nudibranchs. It should be a magic dive experience.
• Dixcart Bay: Sheltered bay with crystal-clear waters and substantial marine life. It is recommended for any level of diversity, from beginners to the most experienced ones.

9. Tabarca Island, Spain

Tabarca Island is small, rocky, and located off the Alicante coast, but it is very rich in maritime history and forms part of some of the most pristine waters within the Mediterranean area. In fact, the entire island forms part of a circumscribed marine reserve that ensures the underwater ecosystem remains healthy and vibrant. It is in these waters that sea bream, groupers, and octopuses swim in this wonderful spot for underwater photography.

Best Spots to Visit:

• Isla Plana: A dive site with an underwater plateau that is wholly carpeted with meadows of seagrass, wherein a variety of marine life is called home.
• La Llosa: Several underwater pinnacles well-populated with life, including barracudas, moray eels, and octopuses.
