Vransko Lake – one name, two locations
December 8, 2025Are you a diving enthusiast looking for new underwater spots to explore? Or perhaps a beginner searching for interesting yet easy diving locations? The crystal-clear Adriatic Sea, with its rich and colorful marine life, numerous archaeological sites and shipwrecks, and warm temperatures, is every diver’s dream.
Read on to discover the 4 locations we’ve selected as the best diving spots on the Croatian islands.
Island of Hvar
One of the most beautiful islands in Croatia, and in Europe, is a popular destination for diving enthusiasts from all over the world. Several underwater sites here enjoy a global reputation.
Vela Grčka Bay hides in its depths a cave inhabited by a rich variety of marine flora and fauna. The entrance to the cave is located at a depth of 10 meters. This diving site is suitable for beginners.
The Paklinski Islands also offer some fascinating diving locations. The most famous one is near the islet of Vodnjak. In the waters around Vodnjak lies a submerged stone obelisk resembling a bell tower, which is why locals have named it Kampanel. The top of the obelisk lies at a depth of 10 meters. Dive deeper, and you’ll discover a canyon adorned with red gorgonians and a 5-meter-long tunnel.
This diving spot is rich in diverse plant and fish species.
Korcula Island
The island of Korčula also hides impressive natural phenomena and the remains of sunken ships beneath its surface.
In Pudarica Bay, near Lumbarda, lie the remains of the Italian steamboat Garda, which sank in 1938 during a severe southern storm. Scattered parts of the ship can still be found on the sandy seabed.
In the waters around the islet of Majsan, which was once an important anchorage in the Adriatic Sea, there is a rich archaeological site. Traces of the Romans remain in the form of amphorae and an anchor located at a depth of 35 meters. Due to sand and stones, visibility is not ideal, but because of the shallow depth, this location is suitable even for beginner divers. It is also rich in marine life, including scorpionfish, flounders, torpedo rays, and other fish species.
Cave enthusiasts should definitely visit the cave in Orlanduša Bay, where they will be amazed by the stunning play of sunlight. Beneath the cave lies a wall that drops to a depth of 40 meters, teeming with fish, crabs, snails, and octopuses.
Island of Mljet
The underwater world of the island of Mljet offers a unique experience for every diver. It is well known that the legendary oceanographer Jacques Cousteau was so enchanted by the island that he declared it to be one of the most beautiful diving sites in the world!
Odysseus’ Cave is one of the most fascinating diving spots on Mljet, named after the Greek hero Odysseus, who, according to legend, lived on the island for seven years with the nymph Circe. The underwater area of the cave is home to a diverse marine ecosystem – southern winds bring jellyfish, while anchovies and octopuses live in and around the cave.
Dive into the cave during the day, and you’ll witness an impressive display of light created as sunlight strikes the cave’s side openings.
Another interesting site is Goli Rat Cape. This location is attractive for the remains of an ancient ship and the amphorae it carried. Less experienced divers can explore the shipwreck remains, while more advanced divers can follow the wall that descends to a depth of 40 meters, ending with a rocky seabed.
Island of Lastovo
The neighbor of the island of Mljet, the island of Lastovo — together with its surrounding islets and Nature Park — also offers several impressive diving locations. Keep in mind that diving on Lastovo is only permitted when accompanied by professional staff from the diving centers Ankora in Zaklopatica and Ronilački raj–Lastovo in Pasadur.
The most famous diving location on Lastovo, and one of the most beautiful in Europe, is the islet of Bijelac. What appears to be a single island on the surface splits underwater into two parts that reach depths of up to 60 meters. Here you’ll find gorgonians and sea stars, while coral adorns the walls. Among the marine life, you can spot moray eels, lobsters, and groupers.
