The Vassilios T is a 105-metre shipwreck resting on a sandy seabed near Komiža. Sunk in 1939 while carrying coal, the vessel lies on its port side with depths ranging from 22 to 55 metres, averaging 40 metres. This advanced dive requires boat access and involves navigating an overhead environment. Divers should be prepared for mild currents and visibility between 15 and 30 metres. Water temperatures fluctuate between 14C and 18C, with cold upwellings at depth often making a drysuit advisable. Due to the significant depth and wreck structure, divers must manage decompression requirements and potential entanglement hazards carefully.

Velika Špilja is a cave and cavern system located near Komiža, Croatia, featuring a wall that descends to 35 metres. This site offers a varied profile suitable for intermediate divers, with mild currents and visibility ranging from 10 to 25 metres. The cavern interiors are generally well-lit, allowing for navigation along the walls. Divers should exercise caution when moving through the cavern to avoid contact with the rock and coral surfaces, which are sharp. Protective gear is recommended to prevent injury from these edges.

Stupiste, located off Vis Island, features a combined reef and wall structure that descends from 19 to 35 metres. The site is characterised by its lack of current, allowing for a relaxed, exploratory dive along the wall profile. Visibility at the site ranges from 10 to 30 metres. Water temperatures fluctuate between 14 and 19 degrees Celsius, necessitating appropriate thermal protection. Access to this site is exclusively by boat, and divers should coordinate entry and exit procedures with their skipper. Given the depth range, this site is suited to intermediate divers who should monitor their bottom time and depth profile carefully throughout the dive.

Ploce is a deep wall and cave site located off Komiža, Vis Island. The topography features a steep wall descending from 28 metres to 70 metres, requiring advanced certification and precise buoyancy control. Divers encounter moderate currents and must navigate overhead cave environments. Visibility varies between 10 and 50 metres. Due to water temperatures ranging from 14 to 18 degrees Celsius, a drysuit or a 7mm wetsuit with a hood is recommended. Access is strictly by boat. Divers should monitor gas consumption closely and brief guides on current direction before descent, as conditions at depth can differ significantly from surface observations.

Gaće, located near Komiža, Croatia, provides a diverse underwater environment featuring a wall, a cave, and sections suitable for drift diving. The site is accessible only by boat and is well-suited for beginners, with depths ranging from the surface to 25 metres and an average depth of 15 metres.
