The John Gilmore is a deep wreck resting upright on a sandy seabed off the Istrian coast. With depths ranging from 30 to 44 metres, this site requires advanced diving skills and precise buoyancy control. Visibility typically spans 15 to 25 metres, allowing divers to view the hull profile clearly. The structure is colonised by sponges and provides habitat for scorpionfish, conger eels, nudibranchs, and California spiny lobster, while schools of bogues frequent the superstructure. Access is by boat only, and divers should be aware of the risk of entanglement when exploring the wreckage. Mild currents generally prevail, though the depth necessitates careful gas management throughout the dive.

The Giuseppe Dezza is a shipwreck located off the coast of Istria, Croatia, resting at depths between 28 and 37 metres. This site is strictly for advanced divers with deep-diving certification. Access is exclusively by boat, as the wreck lies approximately 18.5 kilometres from the shore. Divers should be prepared for moderate currents and variable visibility, which typically ranges from 10 to 15 metres. The wreck structure requires careful buoyancy control to avoid entanglement. Given the maximum depth of 37 metres, divers must plan bottom times conservatively, maintain sufficient gas reserves for safety stops, and monitor depth gauges closely throughout the dive.

The Varese is an upright wreck resting on a sandy bottom at depths between 33 and 42 metres. This advanced dive requires careful planning due to the significant depth and moderate currents. The structure is heavily colonised by gorgonians and sponges, with various fish species inhabiting the hull and superstructure. Divers must manage potential entanglement risks within the wreck and remain vigilant for boat traffic during ascent. Visibility typically ranges from 10 to 15 metres. Given the depth and conditions, this site is strictly for experienced divers equipped with a reel and surface marker buoy.

Wreck Romagna is a cargo ship resting on the seabed at a maximum depth of 43 metres. This advanced dive requires careful gas management and buoyancy control. The wreck structure is extensive, allowing for multiple dives to explore the hull and superstructure. Divers should be aware of variable currents and potential hazards including silt and restricted exits during penetration. Surface conditions require vigilance due to boat traffic in the area. Access is by boat only. The site is best suited for experienced divers capable of managing deep-water environments and decompression requirements.

The Varese is a wreck site located 25 kilometres off the coast of Pula, Croatia. Resting at depths between 32 and 40 metres, this site is strictly for advanced divers. The vessel serves as an artificial reef, with sponges and gorgonians colonising the hull. Divers may encounter scorpionfish, conger eels, and snowflake morays within the wreckage, while saddled seabream and yellowtail damselfish inhabit the surrounding water column. California spiny lobster are also found in the shadows. Conditions include mild currents and variable visibility that can drop to zero. Due to the depth and potential for low visibility, divers must maintain excellent buoyancy control and carry a torch and surface marker buoy.

The Remorker is a wreck dive located off the coast of Pula, Croatia, resting at depths between 35 and 37 metres. This site is suitable for advanced divers only, requiring boat access and careful management of bottom time. Visibility typically ranges from 10 to 20 metres, allowing for observation of the hull structure. Divers should be aware of the potential for entanglement within the wreck and maintain strict buoyancy control. Due to the depth and water temperatures, which fluctuate between 11 and 18 degrees Celsius, appropriate thermal protection is recommended for this 40-minute dive. The site experiences mild currents.

The Baron Gautsch is an Austro-Hungarian passenger ferry that sank in 1914 after striking a mine. Resting on a sandy seabed at depths between 28 and 40 metres, the wreck remains largely intact. Divers encounter a moderate current that can strengthen unexpectedly, requiring boat-based entry and exit. Visibility typically ranges from 5 to 10 metres. Due to the depth and the overhead environment within the superstructure, this site is strictly for advanced divers. Proper buoyancy control is essential to navigate the wreck safely while managing decompression obligations and the risks of nitrogen narcosis. A surface marker buoy is required for the ascent due to local boat traffic.

Kanjon in Pula, Croatia, offers a diverse underwater landscape featuring a combination of reef, wall, and cave formations. The site reaches depths between 3 and 25 metres, making it suitable for intermediate divers. Visibility is highly variable, ranging from 10 to 50 metres, with mild currents typically present. Access to the site is by boat only. Divers should maintain precise buoyancy control and wear protective gear to avoid contact with sharp coral and rocks on the substrate. Water temperatures fluctuate between 12 and 20 degrees Celsius throughout the year, necessitating appropriate thermal protection depending on the season.
