FAQ
What certification do I need to dive the Blue Cave on Bisevo?
An Advanced Open Water certification with cave or cavern diving experience is recommended, although the maximum depth is only 20 metres. The cave environment requires good buoyancy control and comfort in overhead environments. Several dive centres on Vis island offer guided cave dives with proper briefings.
When is the best time to dive the Blue Cave?
The best time for the blue light phenomenon is between 11 a.m. and noon from May to September, when sunlight enters the underwater opening at the optimal angle and reflects off the white seabed. Summer months offer warmer water temperatures around 22 to 25 degrees and calmer sea conditions.
Can I snorkel or only scuba dive in the Blue Cave?
Both snorkelling and scuba diving are possible. Tourist boats regularly enter through the artificial entrance for sightseeing, while divers can access the cave through the original underwater entrance. The diving experience is unique because you swim through the submerged passageway and emerge inside the illuminated grotto.
What certification do I need to dive Svetac Island?
Advanced Open Water certification is the minimum requirement, with Deep Diver specialty strongly recommended. The remote location, exposed conditions, and depths exceeding 40 metres demand experienced divers with good open-water skills. Prior consent from the Croatian Ministry of Culture is required as the island is a protected site.
How do I arrange a dive at Svetac Island?
Diving at Svetac requires prior consent from the Croatian Ministry of Culture and must be arranged through authorized dive operators based in Komiza on Vis island. The boat journey from Komiza takes approximately one to two hours depending on sea conditions. Trips are weather-dependent and typically limited to the calmest summer months.
