Diving Iž Island Walls
Site Overview
Iž Island Walls is a wall dive site in Northern Dalmatia - Zadar & Kornati, Croatia, set in the clear, fish-rich waters of the Adriatic Sea. The Iž island walls are pristine rocky slopes off a quiet Dalmatian island. Lobsters and octopus hide in the cracks, and the clear water makes for relaxed diving. The site suits a range of levels on its shallow parts, with deeper slopes for Advanced. Visibility is excellent, showing the rocky topography and fish clearly. The island’s tranquillity keeps it uncrowded. It is a peaceful natural dive away from the busier wreck sites. 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 14 and 25 degrees Celsius depending on season and depth. The marine life is classic Adriatic, centred on european lobster, common octopus, two-banded seabream, with the full community described below for those planning a dive. Because of its intermediate rating and the need for Advanced Open Water certification, Iž Island Walls 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 Veli Iz, and divers should check in with a local centre before entering the water. The Iž island walls are pristine rocky slopes off a quiet Dalmatian island. Lobsters and octopus hide in the cracks, and the clear water makes for relaxed diving. The site suits a range of levels on its shallow parts, with deeper slopes for Advanced. Visibility is excellent, showing the rocky topography and fish clearly. Plan your profile around a maximum depth of 45 m and an average of 25 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 on the outer slope is a real consideration here. Take a moment to review the site-specific hazards with your guide, because conditions at Iž Island Walls 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 Zadar Hospital Hyperbaric Chamber."

Traveler Notes
Who is this for?
Iž Island Walls 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.
