The Tihany is a wreck located in the Kvarner Gulf, resting at depths between 18 and 45 metres. This site is strictly for advanced divers, as the structure creates an overhead environment requiring specific wreck training and buoyancy control. Visibility typically ranges from 10 to 30 metres. Water temperatures are cool, fluctuating between 12 and 17 degrees Celsius, necessitating appropriate thermal protection. Access is exclusively by boat, and divers must be self-sufficient with a dive computer and surface marker buoy. The wreck provides a habitat for various reef fish and invertebrates common to the region.

Misnjak, also known as Sanddüne, is a reef site located in the Kvarner Gulf near Cres and Lošinj. This site is characterised by shallow, calm waters, providing a suitable environment for newly certified divers to practice buoyancy and basic skills. Access is by boat only. Water temperatures fluctuate significantly throughout the year, ranging from 12C in March to 26C in August, requiring appropriate exposure protection for the season. Visibility and currents at this site are variable, so it is recommended to check local conditions before planning a dive. The reef supports a variety of local reef life.

Srakane Cave is located on the south-west side of Male Srakane island in the Cres and Lošinj region. The site features a cave entrance at 9 metres depth, leading into a 20-metre-long passage that opens into a small gallery with sunlight filtering from above. Nearby, a marine wall descends to 40 metres. This site is suitable for advanced divers due to the overhead environment and depth. Access is by boat only, with the site situated 15 metres from the shore. Divers can expect mild currents and visibility ranging from 10 to 25 metres. Water temperatures fluctuate between 12C and 17C throughout the year.

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.

Srakane Wall is a vertical reef formation located on the southwest side of Male Srakane in the Kvarner Gulf. This site features a steep wall that drops from 5 metres down to a maximum depth of 45 metres. Situated 50 metres from the coastline, the site requires boat access. Divers can expect mild currents and visibility ranging between 10 and 30 metres. Water temperatures are cool, fluctuating between 12C and 17C throughout the year. Due to the depth and potential for strong currents, this site is suitable for advanced divers. Typical dives at this location last approximately 45 minutes.

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.

White Wall in the Kvarner Gulf is defined by a pale limestone wall that descends from 25 metres to a maximum depth of 45 metres. The site features a combination of wall, cave, and reef topography. Divers should note that visibility typically ranges between 5 and 10 metres. Due to the depth, careful management of bottom time and adherence to certification limits are required. Access to this site is by boat only to avoid surf breaks at the shore. Strong currents can occur, requiring constant monitoring. Water temperatures remain between 12 and 17 degrees Celsius, making a drysuit or a 7mm wetsuit necessary throughout the year.

Zabodaski is a reef and wall site located in the Kvarner Gulf. The topography features a reef that transitions into a wall, dropping from 5 metres to a maximum depth of 40 metres. This site is suitable for intermediate divers, as the current remains mild throughout the area. Access is exclusively by boat, which must be arranged in advance. Water temperatures fluctuate between 12 and 17 degrees Celsius, requiring appropriate thermal protection. Visibility at the site is variable, so divers should confirm current conditions with their boat operator before departure. As there are no facilities on-site, all necessary equipment must be carried on the boat.
