THE CITADELS OF THE PONOR

The citadels of Ponor(Cetățile Ponorului) are a fascinating natural site, popular with speleologists. It's one of Europe's most grandiose karstic landscapes, with waterfalls and astonishing formations, along an underground river that runs through a 4 km tunnel. It's reached by a beautiful hike, very rugged in places, starting from Cabana Padiș (12 km, 6h, blue dot marking). Boulders over 70 m high mark the entrance to the cave. To explore it, it's best to be accompanied by experienced cavers.
