Biševo - Blue Cave (42° 58.5'N; 16° 01'E)
Approximately 3 nautical
miles southwest of the island of Vis, you will find the small island of Biševo. There are
some small villages on this island that largely consists of bare rocks. However, the
eastern side houses an interesting natural phenomenon called Blue Cave (Modra Spilja).
There is a narrow
entrance to the cave, accessible via dinghy. However, under the waterline, there are
various entrances towards the cave as well. As a result, around noon on a sunny day with
calm seas, rays of sunlight enter the cave from below. Reflecting on the white stone, it
creates wonderful blue light in the cave.
