The Hans Schmidt is a steamship wreck located off the coast of Istria, Croatia. Resting at depths between 28 and 43 metres, with an average depth of 40 metres, this site is strictly for advanced divers. Access is by boat only, as the wreck lies 22 kilometres from the shore. Divers encounter mild currents and visibility ranging from 10 to 15 metres. The structure provides an overhead environment with risks of entanglement, requiring careful navigation. Water temperatures at depth remain cool, typically around 12C. The wreck serves as a habitat for various reef fish and invertebrates typical of the region.

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.

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.

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.

Lighthouse Peneda provides a diverse underwater environment off the coast of Pula, Croatia, featuring a combination of reef, wall, cave, and seagrass habitats. The site ranges in depth from 4 to 35 metres, with an average depth of 20 metres. Visibility typically spans 10 to 30 metres. This location is accessible only by boat, and guided tours are available through the local dive shop. Divers should be aware of moderate currents and sharp coral or rocks present across the reef and wall sections. A wetsuit is recommended due to water temperatures ranging between 11 and 18 degrees Celsius.
