Visit to the Etna top craters

There are several ways to visit the Mt. Etna top craters, both from the North and from the South side.
Starting point for the North side is Piano Provenzana and for the South side Rifugio Sapienza.
Northern tracks are more beautiful and allow to get up to the highest crates (3300 mt). These tracks are only open in the summer.
Southern tracks are more famous, more scenographic and comfortable.
