Odysseus cave or Pit is a cave on the island of Mljet . It is located on the southern coast of the island, near Babino Polje. The Odysseus cave is an oval shaped cave with several dozen meters in diameter. There is a collapsed vault that is named after the jama, because while looking on the land side, it looks like a big hole in the ground. The bottom is filled with the sea. Through the limestone layers, separating it from the open sea, a tunnel penetration has formed, so once can enter into the cave by a smaller boat.
