Diving Lastovo - Veli Lagoon Wreck
Site Overview
Lastovo - Veli Lagoon Wreck is a wreck dive site in Southern Dalmatia - Dubrovnik & Peljesac, Croatia, set in the clear, fish-rich waters of the Adriatic Sea. The Veli Lagoon wreck is a small sunken vessel at 15-20 m in the Lastovo lagoon. Frogfish and seahorses are associated with the structure, a macro highlight. Its shallow depth makes it accessible to Open Water divers. Visibility is usually good, and the sheltered lagoon is calm. The remote island keeps it uncrowded. It is a gentle, characterful Lastovo dive. Conditions are typical of the Croatian coast: visibility generally runs from 12 to 30 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 long-snouted seahorse, common octopus, small red scorpionfish, with the full community described below for those planning a dive. Because of its beginner rating and the need for Open Water certification, Lastovo - Veli Lagoon Wreck 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 10 minutes near Lastovo, and divers should check in with a local centre before entering the water. The Veli Lagoon wreck is a small sunken vessel at 15-20 m in the Lastovo lagoon. Frogfish and seahorses are associated with the structure, a macro highlight. Its shallow depth makes it accessible to Open Water divers. Visibility is usually good, and the sheltered lagoon is calm. Plan your profile around a maximum depth of 20 m and an average of 14 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 depth requiring awareness is a real consideration here. Take a moment to review the site-specific hazards with your guide, because conditions at Lastovo - Veli Lagoon Wreck 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?
Lastovo - Veli Lagoon Wreck suits beginner divers holding at least an 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.
