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.

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.

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.

The Cesare Rosarol is a deep wreck located off the coast of Pula, Croatia, resting at depths between 45 and 49 metres. This site is strictly for advanced divers due to the significant depth, decompression requirements, and potential for strong currents. Visibility at the site typically ranges from 5 to 15 metres. Water temperatures are cold, fluctuating between 11 and 18 degrees Celsius, necessitating appropriate thermal protection. Divers must be prepared for an overhead environment with entanglement risks and the effects of nitrogen narcosis. Access to the wreck requires a boat charter, and careful planning of bottom time and gas supply is essential for safety.

Galijola is a boat-accessible site off Pula, Croatia, featuring a diverse topography of reefs, walls, and canyons. Divers can explore depths ranging from 8 to 50 metres, with an average depth of 15 metres. The site is characterised by canyon sections that channel between rock faces before opening onto a deeper wall. Conditions include mild currents and visibility between 10 and 30 metres. Due to the significant depth and sharp coral, intermediate skills and careful buoyancy control are required. Water temperatures remain cool, ranging from 12 to 17 degrees Celsius, making a thick wetsuit or drysuit advisable for the typical 45-minute dive.

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.

The Rossarol 1 is a wreck site featuring the remains of an Italian destroyer built in 1913. The vessel struck a mine in 1918, which split the ship into two sections. Divers can explore the larger fore part, which lies capsized and oriented towards the north. The wreck sits at depths ranging from 40 to 50 metres, with an average depth of 47 metres. This site is accessible only by boat and is situated 2160 metres from the shore. Due to the depth, potential for entanglement, moderate currents, and variable visibility between 3 and 15 metres, this dive is strictly for advanced divers.

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.
