Vis

Diving Vis is a boat operation out of the island's two harbours, and the day is built around wrecks rather than reefs. Centres typically run one deeper dive on a hull followed by something shallower on rock or in a cavern, with nitrox commonly used to make the profiles work. Some of these wrecks are protected as cultural heritage and are dived with a licensed centre under permit rather than independently, so the plan is agreed before anyone gets in the water.

The seabed around the island is Adriatic karst: pale limestone dropping away in steps and slabs, undercut with arches and caverns, giving way to sand and silt where the wrecks lie. Cool, clean water and mild current have kept them well preserved and the visibility long. The flip side is that the water stays noticeably cooler than the southern Mediterranean, and the season is correspondingly short, running roughly mid-April to mid-October.

The wrecks carry the trip. The steamship Teti sits at around 32 m and demands a proper plan; a Junkers Ju 87 Stuka found in 2014 lies on the bottom with its shape still legible; and a B-24 Liberator rests deep enough to be firmly technical. Zelena Špilja, the Green Cave, is the counterweight to all that metal — an arch and cavern where the filtered light turns green, which is exactly what gives it its name.

This is a destination for wreck divers who already have depth experience. Advanced Open Water plus a wreck course is a fair minimum, the deepest sites are technical, and good buoyancy matters around silty interiors. Divers after warm water, easy shore entries or heavy fish life will be better served elsewhere in the Mediterranean. Anyone drawn to intact metal, cool clear water and military history is in the right place.
