Snorkelling

Safety notes

Scuba diving is prohibited inside the Blue Cave for preservation and visitor-safety reasons (confirmed via the site's own FAQ), with rare exceptions only for permitted scientific research; one aggregator listing conflicting generic dive-site stats for this location appears unreliable and is contradicted by the official/tourism sources

Permits & fees

No scuba permit applies since diving is not permitted; boat tour entrance fee approx. EUR 13 adults / EUR 8 children (peak July-August pricing), lower off-season

Permits and operators change - confirm before booking.
