Vis Island
Croatia · Adriatic Sea
Vis is the most remote inhabited Croatian island and the country's best diving — Adriatic walls, the B-17 bomber wreck and several other WWII sites, and Mediterranean fish life on clear water.
How this reef is doing
ⓘ How we measure thisReef state
Adriatic wrecks and caves. The reef is algae, sponge, and gorgonian — coral cover is not the right metric.
