Thanks to good visibility diving in Adriatic could be a rewarding experience. Croatia boasts more than 100 diving sites. Its undersea life is rich and diverse. Sandy beaches include species like sea urchins, starfish, shellfish, and much more. Reefs, ship and plane wrecks are popular among divers as well as mysterious underwater caves. A highlight of underwater experience in Croatia could be the dive in the Blue Сave (Modra špilja) on the island of Bisevo. Between 11 a.m. and noon. The sunlight reflects through the water coming from the white floor of the cave and colours it in blue light. Although it’s possible to dive in Adriatic at any time, summer is the most favourable season because of the warmer waters and smaller waves. So the best time to dive is June-September.
