Biševo (Blue Cave)

The Cave has been described by Ransonet and is located in Balun Bay
on the eastern part of the island of Biševo. It has been open to the public since 1884 when the external entrance was cut into the cave and through which the cave can be reached by means of a small rowing boat. When the sea is calm and the day is sunny, reflected sun rays pass through the undersea entrance to the cave and create a fascinating blueness, whilst an immersed object on the sea's surface adopts silverfish sheen.
