Diving Dubrovnik - Bezdan Cave
Site Overview
Dubrovnik - Bezdan Cave is a cave dive site in Southern Dalmatia - Dubrovnik & Peljesac, Croatia, set in the clear, fish-rich waters of the Adriatic Sea. Bezdan is a deep-water cavern off Dubrovnik with stalactites, swim-throughs and light beams. The cavern offers a taste of overhead-environment diving for prepared divers. Light effects inside make it a photogenic, dramatic dive. Visibility is excellent, enhancing the play of light. The site is close to Dubrovnik and convenient. It is a scenic, less-crowded Dubrovnik dive. Conditions are typical of the Croatian coast: visibility generally runs from 15 to 35 metres, the current is low and the water temperature ranges between 15 and 26 degrees Celsius depending on season and depth. The marine life is classic Adriatic, centred on mediterranean cardinalfish, loggerhead sponge, mediterranean moray, with the full community described below for those planning a dive. Because of its intermediate rating and the need for Advanced Open Water certification, Dubrovnik - Bezdan Cave is best approached with the right thermal protection and, where relevant, wreck or deep training. It is a representative example of why Croatian diving, with its wrecks, walls, caves and gorgonian forests, attracts divers who want history and Mediterranean life in equal measure.
Dive Briefing
"Entry is made by boat, with a transfer of about 20 minutes near Dubrovnik, and divers should check in with a local centre before entering the water. Bezdan is a deep-water cavern off Dubrovnik with stalactites, swim-throughs and light beams. The cavern offers a taste of overhead-environment diving for prepared divers. Light effects inside make it a photogenic, dramatic dive. Visibility is excellent, enhancing the play of light. Plan your profile around a maximum depth of 30 m and an average of 20 m, keeping a close eye on gas and, in deeper sections, on the cold thermocline. Buoyancy control matters: silty or vegetated bottoms and submerged structures are easily disturbed, and overhead environment in the cavern is a real consideration here. Take a moment to review the site-specific hazards with your guide, because conditions at Dubrovnik - Bezdan Cave can shift quickly with wind and tide and change the feel of the dive. A safe ascent with a surface marker buoy and a clear exit plan completes the dive, with emergency cover routed through Dubrovnik Hospital Hyperbaric Chamber."

Traveler Notes
Who is this for?
Dubrovnik - Bezdan Cave suits intermediate divers holding at least an Advanced Open Water certification, and it is a strong choice for those who enjoy the clear, fish-rich water of the Croatian Adriatic. Photographers, training groups and divers chasing wrecks, walls, caves or macro life will all find something here, provided they respect the temperature, the marine park rules and the limits of each site. It is less suitable for absolute novices unless booked through a centre running a supervised course, and the deepest or most enclosed sections should only be attempted with the correct specialist training and a guide. Planning a dive here with a licensed Croatian operator not only keeps you safe but also helps protect the fragile gorgonian forests, seagrass and wrecks that make the site special.
