The trail starts from Piano Provenzana, the ski station placed on North Etna. From here you can go (if there's no snow) between 2002 lava flows and the skilift/skichairs, on track you can easily walk on. The tracks goes to "Monte Conca", one of the many old cratres on Etna.
This path allows you to see the "Stone Forest": it's formed by some pine trees which have been "dried" by the lava flow, but not burned. The gray color they have caused people to call them as "stone trees".
The path is quite easy to walk through and is affordable by almost everyone. We just remind you not to go during the winter season.
