Hrid Piramida is a submerged pinnacle located off Krk Island, rising from a depth of 27 metres to within 3 metres of the surface. This site is suitable for beginners, though divers must manage moderate currents and maintain precise buoyancy control. Due to the requirement for boat access and the presence of active boat traffic, the use of a surface marker buoy is essential. Visibility at this location varies depending on prevailing conditions. Divers should monitor their depth gauge carefully throughout the dive to remain within the 3 to 27-metre range.

Plovanov Stol is a wall and reef site located off Krk Island, Croatia. The topography features a drop-off starting at 10 metres and extending to 45 metres. Divers should expect moderate currents and visibility between 10 and 15 metres. Water temperatures range from 12 to 25 degrees Celsius, with potential fluctuations caused by freshwater springs upwelling from the seabed. Access is by boat only, and the site is suitable for beginners. Species recorded around this area include wrasses, scorpionfish, bream, and various crustaceans. Due to boat traffic in the Kvarner Gulf, divers must deploy a surface marker buoy before ascending. Monitor depth carefully throughout the dive.

Kamp Krk on Krk Island offers a shore-entry reef and wall dive suitable for beginners. The site features a wall that descends beyond recreational limits, though the primary area for less experienced divers remains between 10 and 18 metres.

Timos Caves on Krk Island is a boat-access site featuring a series of caverns and caves ranging from 5 to 25 metres in depth. The site presents an overhead environment, requiring divers to carry a torch as natural light diminishes within the system. Conditions are generally mild with light currents, though visibility can vary between visits. Water temperatures fluctuate seasonally between 12 and 25 degrees Celsius. Due to the overhead nature of the site, it is recommended that beginners dive with a local guide who is familiar with the cave layout. Ensure you have appropriate training for cavern environments before attempting to penetrate these areas.

Cavern Bay on Krk Island offers a diverse underwater landscape featuring a cave system, a vertical wall, and a drop-off reaching 25 metres. Divers typically explore the site at an average depth of 18 metres. The cave section presents an overhead environment requiring strict buoyancy control and primary and backup torches due to limited ambient light. Outside the cave, the wall and drop-off provide varied topography. Access is exclusively by boat, and the site is suitable for intermediate divers with cavern certification. Conditions include mild currents and visibility ranging from 10 to 30 metres. Night diving is available, and the site remains accessible throughout the year.

The SS Regolo is a technical wreck dive located off Krk Island, Croatia, resting at depths between 50 and 66 metres. This site requires trimix and advanced technical diving protocols due to the extreme depth and potential for nitrogen narcosis. Access is strictly by boat, and divers must be prepared for variable currents and potentially low visibility. The wreck structure provides a habitat for various marine life, though species recorded around this area include wrasses, scorpionfish, bream, and yellow gorgonians. Given the depth and environmental hazards, including decompression requirements, this site is suitable only for experienced technical divers using professional boat support.

Velo Čelo on Krk Island is a reef site defined by its towering golden cliffs and rocky seabed. Accessible only by boat, the site offers visibility ranging from 15 to 30 metres.
