    CharacterCave dive
    StandoutDramatic cave topography

    The Tunnel dive site in Istria offers a straightforward cavern dive, suitable for divers comfortable in overhead environments. You'll navigate through a dark passage, emerging into an open area with ambient light filtering down. It's a quick, easy dive that gives a taste of cave diving without the technical demands. We'd suggest it for those looking to expand their diving experience beyond open reefs.

    Safety Notes

    Overhead environment - never enter without proper cave/cavern training, redundant equipment, and a guideline.
