The premier destination for deep sea diving and snorkelling in Croatia is the island of Korcula, located in Dalmatia—a narrow stretch on the Eastern shore of the Adriatic Sea which makes up one of the four historic regions in Croatia along with Istria, Slavonia, and Zagorje. Simply put, Korcula is the epicenter of sea diving in Croatia as in addition to dozens of incredible sites and plenty of reputable diving related businesses, it also offers easy access to other local islands with good diving spots.
The island of Korcula is anchored on the Western side of Croatia smack dab in the middle of a bay that’s dotted by smaller islets and surrounded by tranquil and serene coves. From this central point you can choose from more than 35 different and extremely diverse diving areas.
These include shallow underwater caves, walls with overhangs, reefs and a wide variety of marine life that includes colorful ocean sponges, gorgonian coral (red coral) and many more stunning underwater formations and wildlife. Two of the most popular caves are Blue Hole and Big Cave. For a more mellow underwater adventure there are shallow sites with lush sea grasses that are populated by sea horses.
For more adventurous and experienced divers, there are also shipwrecks that can be explored, with a couple notable wrecks being those of the Boca and the Garda. The Boca ran aground un 1984. Both the bow and the stern of the boat are accessible as are its two propellers. It is possible to swim through the wreck and observe the plethora of marine life that has overtaken the hull. Lower down at 23 meters underneath the surface on the Southern side of Korcula is the Garda, an old steamship that was flattened but still reveals a wide variety of marine life for those divers that are willing to rummage through the metal plates.
No matter what your level of skill, experience, and comfort, diving in Korcula offers something for everyone. The majority of the dive sites are locarted near the shore and are easy to get to by boat. One of the most impressive aspects of diving in Korcula is the visibility, which extends for over 30 meters (100 feet)
The currents of the Adriatic sea that surround Korcula are mostly calm and gentle. As for diving companies that offer rentals, guides, and/or boats, these are predominantly located on the South and West sides of the island in charming little towns such as Vela Luka, Lumbarda, and others.
The best time of year to go diving, sailing and do other sea activities in Korcula is between May and November. During the summer months the temperature of the water rises to approximately 24 degrees celsius (75 degrees fahrenheit). Later in the fall the temperature drops slightly to 20 degrees celsius.
As for getting to Korcula, there are many different modes of transportation from the Croatian mainland and the Dalmation coast. Most travellers rely on busses travelling out of Dubrovnik and the ferries that leave in the early morning hours from Split and Hvar.
