02Blue Grotto

Swimming in crystal waters inside a secluded cave is an experience you won’t forget. The Blue Grotto cave in Luštica Peninsula allows you to do both. The 29-foot-high Blue Grotto gets its name from the mesmerizing effect the reflecting light has on the clear water. There are various kayak and boat tour operators in the vicinity that provide trips to this magical cave.
