Tunnel von Prvic is a shallow boat-accessed tunnel dive on the north side of Prvic Island, built around a scenic swim-through with colourful sponge growth and a fish-rich wall. The site suits divers who want an easy depth profile but still need good buoyancy and calm tunnel etiquette. Octopus, conger eels, nudibranchs, scorpionfish, and schools of small reef fish are regular highlights around the rock and the passage.

Safety Notes
Use appropriate precautions for an overhead tunnel section. Keep buoyancy steady, stay spaced out, and treat the swim-through as a controlled dive rather than open water wandering.
Access Restrictions
Best for divers comfortable with tunnel swim-throughs and buoyancy control; not a site for casual wandering inside the overhead section.
Legal Notes
Follow skipper guidance on anchor position, tunnel entry, and diver spacing.
