Divers typically begin at a depth of 5 metres, descending vertically along a reef to reach the wreck, which rests on its port side at a depth of 35 metres. The bow is buried in the sand, and the site reaches a maximum depth of 45 metres. Due to the depth and the overhead environment of the wreck, this site is suitable for advanced divers only. Boat access is required to reach the location. Conditions vary, with visibility ranging from 5 to 30 metres and mild currents present.

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.

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.

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.

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.

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.

Susak-secca Margarina is a wall and reef site in the Kvarner Gulf featuring a rapid depth drop-off from 5 to 40 metres. This site requires boat access due to its distance from shore and the presence of strong currents that can occur throughout the area. Divers and snorkellers should monitor current direction before entry, as flow patterns significantly impact the dive. Due to the depth and current, this site is suited for intermediate divers. Water temperatures range between 13C and 18C, and a 5mm wetsuit or drysuit is recommended as temperatures drop noticeably below 20 metres. Always use a boat for entries to avoid navigation risks.
