The surroundings of the Cason di Lanza pass, accessed from Paularo, offer an incredibly interesting landscape from a geological point of view; the area is part of the Carnic Alps Geopark.

In this area it is not difficult to observe superficial and hypogeous karst phenomena; in fact, the Attila cave opens up in this area, a cavity that is prevalently horizontal and over 450 metres long. The cave is very narrow (practically a swallow-hole) and can be visited with torches for just a few metres, as it narrows more and more as one proceeds, and can be reached by means of four different itineraries that start out from behind the Casera Cason di Lanza cheese factory. The routes are easy, also suitable for children.
Not everyone knows that Attila, leader of the Huns, was undoubtedly famous for his aggressive military policy. After he had almost completely folded the territories of the Eastern Roman Empire, on 8 June 452, he retreated towards present-day Hungary, passing right through the Pian di Lanza.
According to legend, he deposited his immeasurable treasures, the fruits of his raiding campaigns, in the very cave that bears his name.
