Odysseus' Cave

Daylight pouring through the side openings of a legendary sea cave

Odysseus' Cave is a marine cave on the southern coast of Mljet, near the village of Babino Polje, named for the legend that the hero spent seven years on the island. It is a shallow dive of no more than 6 m into a sunlit chamber, and divers come for the play of light through its openings and the octopuses living around it.

Also known as Odysseus Cave, Ulysses' Cave, Odisejeva špilja.

The dive

The way in is a narrow, tunnel-like passage only 4 to 5 m wide that leads from the open sea into a chamber formed where the cave's vault collapsed. Inside, the whole dive stays shallower than 6 m.

By day the chamber becomes a light show: sunlight strikes the cave's side openings and lights the water, at its brightest around midday when the sun is high enough to shine straight down. Anchovies and octopuses live in and around the cave.

What certification does Odysseus' Cave need?+
