The Piccola Cassia route, descending from the Pieve di Samoggia, can be quickly accessed near the stream, just upstream of Savigno. At the Cà Mario bridge, there is a notable geosite, where the Samoggia riverbed flows confined between striking vertical rock layers. The route then ascends toward the church and the village of San Prospero, the historic castle of Savigno. The surrounding area contains several remnants and ruins of ancient houses and churches.

San Prospero overlooks the Samoggia valley from a strategically panoramic position. The ancient castle of Savigno di Sopra once stood here, and nearby were the Church of Santo Stefano and the hamlet around the Church of San Martino. The Church of San Prospero suffered several destructions and was rebuilt in its current form at the end of the 17th century, while the bell tower was completed only in the 19th century.

Nearby, notable features include the historic rural hamlet of Melodello, with a 16th-century tower, and a small votive stone pillar called the “Maestà del Melodello” along Via Straccadora. This road still leads to Savigno, passing through a lush coppice woodland, favored by a cool and humid microclimate even in summer.

On the ridge between the Samoggia and Lavino valleys, on a viewpoint overlooking the hill of San Prospero, stands the Church of the Holy Trinity of Savigno, first documented in 1068. The church was rebuilt in 1336 following a fire. Subject to disputes among the Pieve of Samoggia, the Pieve of Roffeno, the Abbey of Santa Lucia, and Nonantola, it was downgraded to an oratory in 1650. After sustaining damage during the Second World War, the area used for worship was reduced to the apse alone.

Near Casa Bortolani, the two Piccola Cassia routes from Monteveglio—ascending the opposite ridges along the Samoggia valley—rejoin. Shortly after, the route reaches the Oratory of the Holy Trinity, situated on a hill offering wide panoramic views. On the Venola stream, the 17th-century Mulino del Dottore is still in operation, with water-driven stone millstones.

Tolè has long been celebrated for its springs and today hosts an open-air museum in the historic village, featuring fountains and painted works on the walls of the houses. The Piccola Cassia route passes through the village center; of particular interest near the church is a boundary stone placed in 1616, after years of violent border disputes, at the point determined by surveyors appointed by the legates of Pope Paul V and the Duke of Modena, later moved here in the early 1960s.

Downstream, the route rises along the two ridges of the Samoggia, while continuing toward the Abbey Church of Santa Lucia, a stop and place of hospitality for pilgrims.
