Diros caves are the most beautiful caves in Greece, and one of the best in the world as well. The Vlihada cave is the only one open to the public. The entrance is a narrow passageway and is few meters above the sea. From the entrance, the sightseers have to pass numerous chambers and arches while enjoying various stalactites and stalagmites in a very creative formation. The cave is 3.5 km long and has a temperature of 18 degrees C. (Peloponnese, Greece / 2007).
