Hellenistic Port is a shore-access archaeological dive in front of Hotel Issa on Vis, where an ancient harbour sits under a concrete quay, a yellow-sponge slope, and a shallow plain that opens into the bay. The site works well as an easy daytime dive or a night dive, because the harbor remains hold sponges, amphorae, groupers, scorpionfish, octopus, conger eels, squid, and other Adriatic life without needing a long boat ride. Divers should treat it as a relaxed harbour exploration with careful shore entry and good surface awareness rather than as a deep wreck or drift dive.
