-ACCESSIBLE-
The Piani di Ragnolo, one of the most beautiful areas of the Sibillini Mountains, insist on the Municipalities of Fiastra and Sarnano and are a well-known destination for cross-country skiing lovers (there are five rings, for a total of 22 km of route) and walks. Up to fifty different types of orchids can bloom here in late spring. The path to reach the Piani is part of the Great Ring, it can be practiced in any season.
Here on 20 July 2017 the Paola Turci concert was held as part of the Risorgimarche events promoted by Neri Marcorè.
