Passo delle Radici is a high mountain pass at an elevation of 1.529m (5,016ft) above the sea level, located on the boundary of Emilia-Romagna and Tuscany regions, in central Italy.
Nestled in the Italian Apennines, the road to the summit is totally paved but pretty narrow (closed to trucks). It’s called Strada Provinciale 72 del Passo delle Radici (northern side) and Strada Provinciale 324 (southern side).
The pass road is 37.5km (23.30 miles) long, running from Castiglione di Garfagnana (in the province of Lucca) to Pievepelago (in the Province of Modena). The drive is steep, hitting a 10% through some of the ramps.
