The cave's passageways, discovered in the early 1940s by locals hiding from the Nazis, extend for more than 1 km (½ mile) under the hills. You learn about the high caverns and multihued limestone stalagmites during the 45-minute guided tour; one begins about every 15 minutes. Printed English-language information is available. Be prepared for the many steps you must walk up on the way out. At the information center you can see some of the paleontological finds from Perama and learn more about the geology of caves. Bus No. 8 from Ioannina's clock tower gets you here.
