Scuba diving in Blue Cave

Blue Cave is located on the east side of the island, and it is one of the natural beauty spots that surely shouldn't be missed. Blue Grotto was originally accessible by diving through an only underwater entrance. Later, an artificial entrance was built and it is large enough even for small boats. The best time to visit Blue Grotto is between 11a.m. and 12 noon, when the sunlight, passing through an underwater opening and reflecting back from the white bottom, illuminates the cave in bright aquamarine light. At the same time, the objects in the water have a silvery shimmer.
