Monte Osero CAI 181 Loop

The trail officially starts from the church of S. Lorenzo in Calenzano (703m above sea level). You can typically find parking in the village near the church, which serves as the trailhead.

The terrain is quite varied. It begins on a roadway, transitions to a track, then a country road, and finally becomes a more steep and strenuous path through beech woods and broad open pastures. The very last ramp to the summit is rather steep. You'll encounter unpaved paths, roads, and natural trails.

While the trail has some steep and strenuous sections, particularly towards the summit, its overall difficulty is generally considered 'moderate' and 'excursionist'. It's suitable for individuals with a minimum level of training, but beginners should be prepared for the uphill challenge.

Along the route, you'll pass through serene beech forests and areas of reforested conifers. From the summit, you'll be treated to magnificent views of the Perino valley, the rugged peaks of the Concrena, and numerous small villages. The summit itself features an expansive meadow with a distinctive solitary tree and a small shrine. You'll reach the summit of Monte Osero.

Yes, beyond its natural beauty, the trail has historical significance. Monte Osero was a battlefield during World War II, and remnants of an American Douglas A-20 Havoc/Boston aircraft have been found on the summit. The summit's solitary tree also houses a small shrine dedicated to the Madonna. Additionally, the trail is part of the annual 'Marcia Longa' route, ensuring good signage.

The trail offers diverse experiences throughout the year. Spring, summer, and autumn are ideal for enjoying the broad open pastures and beech woods. In winter, the Rio del Buco, a stream crossed by the trail, can transform into a magnificent ice waterfall, offering a unique seasonal attraction for those prepared for colder conditions.

The trail is generally considered suitable for dogs. However, it's always recommended to keep your dog on a leash, especially in areas where you might encounter wildlife or livestock. There are no specific restrictions mentioned regarding dogs on this route.
