Southwest of Bologna, where the flat Po plain meets the first ripples of the Apennines, the hills around Zola Predosa hide a strange geology. These are gypsum hills, made of evaporite rock formed when an ancient sea dried out millions of years ago, leaving layers of shimmering selenite crystals. Water dissolves gypsum easily, and over time it has carved sinkholes, blind valleys and caves through the rock. In 2023, the Evaporitic Karst and Caves of the Northern Apennines were listed by UNESCO, and the Gessi Bolognesi around here are a key part of that story.
The gypsum has been quarried for centuries, and the crystal blocks were used in Bologna's medieval walls and buildings. Today, the hills are a patchwork of woodland, meadows and vineyards, with a few walking trails leading to the sinkholes and cave entrances. The caves themselves are mostly closed to the public, home to bats and fragile formations, but guided visits are sometimes organised by local caving groups. The wine from these hills, Pignoletto, is a crisp white that pairs perfectly with the region's rich food.
For motorcycle lovers, this is holy ground. The Ducati factory and museum in Borgo Panigale are only a few kilometres away, on the western edge of Bologna, and a factory tour is a pilgrimage many riders make. To the south, the hills rise quickly, and roads climb toward the Apennine passes. The SS65 della Futa and the road over the Raticosa pass to Florence are legendary, with endless bends, fast sections and stunning views. These roads are popular on weekends, so expect plenty of company, and be aware of police checks.
Zola Predosa, with sixteen thousand residents, is a busy town with all the services you need, including fuel and supermarkets. Calderino and Riale are smaller villages nearby. Bologna, just a short ride away, is the capital of Italian food, so make time for tagliatelle al ragù, tortellini in brodo and mortadella. Avoid riding in the city centre, which is restricted to traffic, and instead park on the outskirts and explore on foot.
