It was well-known to local fishermen, who in 1884 showed it to the Austrian artist, explorer, and speleologist Eugen von Ransonnet-Villez [de], who published an article in the Viennese daily Neue Freie Presse declaring that its beauty surpassed even that of Capri's famed Blue Grotto.

This cave is difficult to spot when cruising away from the shore, due to the unusually narrow, almost vertical, 30 m high opening in the stone gorge.

The interior of the cave consists of a main, spacious hall and a low winding canal which, after about 70 m, ends with a small beach.

Biševo, along with Vis, Sveti Andrija and its neighbouring islet of Kamnik, Brusnik, Jabuka and the Palagruža archipelago, forms part of the Croatian Offshore Islands Important Bird Area (IBA).

This was designated as such by BirdLife International because it supports significant breeding populations of Scopoli's and Yelkouan shearwaters, as well as of Eleonora's falcons.
