The Blue Cave or Modra Špilja in the small island of Bisevo, Croatia is
one of the most extraordinary caves in the world. For the most part,
it’s unlike your usual cave that’s damp, dark, and brown-colored. As you
might have guessed, Bisevo’s Cave is blue, but not because of some
abnormality in the rock’s mineral content or some blue organism covering
the cavern walls. For all you know, it would be dark, damp, and
brown-colored all the same, if not for this hole at the bottom which
allows sunlight to filter in through the waters. The effect is an
enchanting blue glow coming from the pool that illuminates the entire
cave with a shimmer. The cave is most dazzling from 11AM to noon on a
sunny day, when the sun is at its best. Nonetheless, the Blue Cave isn’t
as popular as other amazing caves because of its remoteness. To get to
the glowing grotto, you must ride a ferry boat from Croatia to the
island of Vis, where you could catch a bus or rent a motorbike to the
tiny fishing village Komiza. From there, you could hire a boat to the
island of Bisevo, and then get a smaller raft that could fit in the tiny
1.5 by 2.5-meter entrance of the cave. But swimming in a glowing pool
is sure worth the trip, though.
