Once an escape route used by WWII POWs and Italian freedom fighters escaping from Nazi-occupied Sulmona to Allied-occupied Casoli, the Sentiero della Libertà (Freedom Trail) has been turned into a historic long-distance hiking trail that cuts across the peaks and plateaus of the Parco Nazionale della Majella. Well-signposted with red and white markers, the path is 60km long.
The Sentiero starts in the eastern suburbs of Sulmona and is usually tackled over three to four days, with stops in Campo di Giove and Taranta Peligna. Since 2001, a commemorative communal march along the trail has been held in late April, attracting up to 700 people. Registration costs €60; see the website (Italian only) for entry details.
