The site is suitable for intermediate divers and snorkellers, with depths ranging from 3 to 12 metres. Conditions include mild currents and visibility between 10 and 30 metres. Water temperatures fluctuate between 12C and 25C, with the interior of the cave typically feeling colder and more refreshing than the surrounding sea. Access is available via both shore and boat. Divers should be aware of potential hazards including boat traffic, cold water, and the overhead environment.

Miracine, located on Krk Island, offers a combination of reef and cave diving across a depth range reaching 30 metres. Divers can expect visibility between 15 and 30 metres, with mild currents allowing for exploration of both shallow and deeper sections. Entry is from the shore, where caution is required due to potential surge and the presence of sharp rock and coral. Given the water temperatures ranging from 12 to 18 degrees Celsius, appropriate thermal protection is recommended. As there are no confirmed facilities on site, divers should arrive prepared with full tanks and all necessary equipment.

Cres Mezulin, located off Krk Island, offers a diverse underwater landscape featuring a reef, wall, cave system, and drop-off. This boat-only dive site is suited for intermediate divers, with depths ranging from 20 to 40 metres. Visibility typically spans 10 to 30 metres. Divers should be prepared for mild currents that can occasionally strengthen around the wall and cave sections. Maintaining good buoyancy is essential to avoid contact with sharp coral and rocks. Water temperatures remain cool, ranging between 12 and 17 degrees Celsius throughout the year, making a 5mm or 7mm wetsuit necessary for comfort during the typical 45-minute dive duration.

Mali Bok on Krk Island features a dramatic vertical wall and reef topography that drops quickly from the shore. This site is suitable for intermediate snorkelers who can navigate the steep terrain. Entry is via a pebble beach, and water conditions typically involve mild currents. Water temperatures fluctuate significantly throughout the year, ranging from 12C in winter to 26C in August. Species recorded around this area include wrasses, bream, painted comber, and various invertebrates such as sea stars, crabs, and cow snails. Be aware of sea urchins and sharp coral when entering or exiting the water.

The Nanos is a technical wreck dive located off Krk Island, resting at depths between 70 and 93 metres. This site is strictly for advanced divers, requiring trimix certification and decompression procedures due to the significant depth and overhead environment. The wreck structure features various recesses and surfaces that host scorpionfish, conger eels, forkbeard, John Dory, nudibranchs, sponges, and California spiny lobster. Divers must manage gas supplies carefully to mitigate nitrogen narcosis risks. Access is by boat only, and conditions include moderate currents and variable visibility. Thermal protection is essential, as water temperatures fluctuate between 12C and 25C throughout the year.

Zeca is a boat-accessible reef and wall site located in the Kvarner Gulf. The topography features a wall that descends from 10 metres to 45 metres, where it transitions into a significant drop-off. Divers experience mild currents and visibility ranging from 10 to 30 metres. Due to the depth and water temperatures between 12 and 17 degrees Celsius, this site is suited for intermediate divers who should use appropriate thermal protection. Thermoclines are common in the Adriatic Sea, causing temperature variations at different depths. Divers should exercise caution regarding sharp coral and rocks during boat entry and exit.

Cutin is a reef site located in the Kvarner Gulf near Cres and Lošinj. The topography features a wall that descends from 6 metres to a maximum depth of 55 metres, with an average depth of 12 metres. This site is suitable for intermediate divers, offering mild currents and visibility between 10 and 30 metres. Access is by boat only. Divers should be aware of boat traffic on the surface and manage depth carefully to avoid nitrogen narcosis. Water temperatures fluctuate between 12C and 21C throughout the year, requiring appropriate thermal protection. The reef supports a variety of Mediterranean reef fish and invertebrates.

Mali Cutin is a wall and reef dive located in the Kvarner Gulf, offering depths between 28 and 40 metres. The site is characterised by a vertical wall that drops into deep water, requiring boat access for all dives. Visibility typically ranges from 10 to 30 metres. Divers should be aware of the potential for strong currents, which require careful monitoring throughout the dive and precise planning for boat entry and exit procedures. Due to water temperatures ranging from 12 to 17 degrees Celsius, a thicker wetsuit or drysuit is recommended for this intermediate-level site.
