Monte Sillara, Mountain summit in Emilia-Romagna and Tuscany, Italy.

Monte Sillara is a mountain summit rising to 1,861 meters between Emilia-Romagna and Tuscany. Its northeastern slopes contain two alpine lakes, while the southwestern side drops through rocky and exposed terrain.

The peak stands as the highest point in the Appennino Parmense and has long served as a natural boundary between the provinces of Parma and Massa-Carrara. Its position as a border landmark has shaped settlement patterns and mountain use across many centuries.

The summit holds a small stone chapel with a statue of the Madonna, a landmark for those arriving from the Parma side. Looking toward the Lunigiana, the medieval village of Iera (Jera) can be made out below. The peak is the highest point of the Appennino Parmense, a reference for walkers in the area.

The easiest ascent starts on the Parma side; the Lunigiana slope is steep and suited to experienced climbers. From Monte Losanna (1,856 m) and Monte Bragalata (1,835 m) the summit is reached via Passo di Compione (1,794 m), while routes from Monte Paitino (1,815 m) and Monte Matto (1,837 m) cross large drops and cliffs.

From the summit, in excellent conditions, the Wallis Alps (about 250–270 km away), the Bernese Alps (about 285 km) and the Bernina Group (about 225 km) can be seen to the north and northwest, and the mountains of Corsica, such as Monte Cinto, to the south-southwest. The two glacial lakes below the peak, Sillara Superiore and Sillara Inferiore, lie at 1,732 and 1,731 m and are the highest in the Parma Apennines.
