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.

Sika is a multi-terrain site off Komiža, Croatia, featuring a reef, a pinnacle, and a wall that drops beyond 60 metres. Divers typically explore the site at an average depth of 19 metres. The topography includes a wall where gorgonians and large sponges are found, while the reef structure provides habitat for scorpionfish, snowflake moray eels, conger eels, and nudibranchs. Anthias inhabit the shallower pinnacle sections, and dentex are observed in the open water. Conditions include moderate currents and visibility ranging from 10 to 30 metres. Divers should be prepared for thermoclines and boat traffic. This site is suitable for intermediate divers and requires boat access.

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. Visibility at the site typically spans 10 to 30 metres. Divers should remain mindful of boat traffic in the area and monitor their depth throughout the dive. Water temperatures fluctuate between 14 and 20 degrees Celsius, making a 5 mm wetsuit advisable outside of the summer months.

Marinero is a technical wreck dive located off the coast of Komiža, Croatia. Resting at a depth of 80 to 82 metres, this site is strictly for advanced divers capable of managing significant decompression requirements and nitrogen narcosis. Access is exclusively by boat, with the wreck situated over 10 kilometres from the shore. Visibility typically ranges from 5 to 10 metres, and water temperatures remain between 14C and 17C throughout the year, necessitating the use of a drysuit. Divers should expect mild currents and must arrive fully self-sufficient with a robust ascent plan and appropriate gas redundancy for the 15-minute average bottom time.

Anfore, located off the coast of Komiža on Vis Island, is a diverse dive site that combines a natural reef with a wreck and artificial reef structures. The site spans a depth range of 6 to 22 metres, making it accessible for intermediate divers. Visibility typically ranges between 10 and 30 metres, and mild currents generally keep conditions manageable. Access to the site is by boat only, requiring coordination with a local dive operator. Water temperatures fluctuate significantly throughout the year, ranging from 14C in winter to 26C in summer, necessitating appropriate exposure protection for the season.

Mala Travna is a secluded bay on Vis Island featuring a mix of pebble beach and flat stone slabs. The site offers both reef and cave topography, with the rocky coastline to the right of the bay containing small underwater caves and crevices. Divers and snorkellers should be aware of moderate currents and water temperatures that are typically a few degrees colder than surrounding areas due to local freshwater springs and a western current. Depths start at 5 metres. Access is available from both the shore and by boat. Facilities at the site include parking, toilets, a cafe, and equipment rental. Hazards include cold water, overhead environments, sea urchins, and sharp rock formations.
