Diving Mana Island
Site Overview
Mana Island is a wall dive site in Northern Dalmatia - Zadar & Kornati, Croatia, set in the clear, fish-rich waters of the Adriatic Sea. Mana Island is a Kornati islet of underwater cliffs and sea caves in crystal-clear water. The vertical rock and caverns offer dramatic topography for confident divers. Gorgonians and reef fish cover the walls, and the light in the caves is photogenic. A national-park permit is required, arranged through your operator. Visibility is regularly superb, among the best in the Adriatic. It is a scenic, less-crowded Kornati dive for experienced divers. Conditions are typical of the Croatian coast: visibility generally runs from 20 to 40 metres, the current is moderate and the water temperature ranges between 14 and 25 degrees Celsius depending on season and depth. The marine life is classic Adriatic, centred on red gorgonian, mediterranean moray, two-banded seabream, with the full community described below for those planning a dive. Because of its advanced rating and the need for Advanced Open Water certification, Mana Island 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 50 minutes near Murter, and divers should check in with a local centre before entering the water. Mana Island is a Kornati islet of underwater cliffs and sea caves in crystal-clear water. The vertical rock and caverns offer dramatic topography for confident divers. Gorgonians and reef fish cover the walls, and the light in the caves is photogenic. A national-park permit is required, arranged through your operator. Plan your profile around a maximum depth of 60 m and an average of 35 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 deep cliffs with rapid depth gain is a real consideration here. Take a moment to review the site-specific hazards with your guide, because conditions at Mana Island 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?
Mana Island suits advanced 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.
