Species recorded around this area include wrasses, scorpionfish, various nudibranchs, and seabream, which inhabit the reef structure and surrounding water column.

Kormat is a reef site located off Krk Island in the Kvarner Gulf. The topography consists of a reef structure spanning depths between 20 and 40 metres, making it suitable for intermediate divers. Access is strictly by boat. Visibility at the site ranges from 10 to 30 metres, and the area is generally free of currents. Divers should monitor their air consumption and depth closely due to the significant profile. Species recorded around this area include wrasses, bream, two-banded seabream, crabs, sea stars, and various nudibranchs such as the Cratena slug and Mediterranean violet aeolid. Sharks are noted as a potential hazard in this region.

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.

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.

Plava Grota on Krk Island is a sea cave featuring a large underwater entrance and a smaller siphon. This structure creates a distinct blue light effect within the cavern. 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.

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.
