The Campo Imperatore plain enshrines small bodies of natural water of karst and glacial origin. Some of them are perennial, others instead have a rather limited life, connected to the melting period of the snowpack. Among these lakes, perhaps the most famous - doubtless the most photographed one - is Lake Pietranzoni, an example of the marvels of Abruzzo in the heart of the region itself. A kind of “Gran Sasso mirror”: that’s what the fantastic Lake looks like, at about 1,660 meters above sea level, thanks to its peculiarities. The icy and lively waters reflect the nature around, just like a mirror indeed.
