Fodor's Expert Review Cave of Antiparos

In the 19th century the most famous sight in the Aegean was the cave of Antiparos, and it still draws many visitors every year. Greece's oldest known cave sits on the southeastern part of Antiparos. It's filled with shapely stalactites and stalagmites of which the oldest is said to be 45 million years old. The natural wonder was first discovered by a French ambassador in the 16th century and myths, legends, and stories have been associated with it along the way. You'll need to take exactly 411 steps down into the cave's 100-meter-deep core to explore. Look for Lord Byron's autograph. Outside is the church of Agios Ioánnis Spiliótis, built in 1774. Audio tours are available.
