The ride through the famous Via Mala Gorge is a true highlight for road cyclists. The narrow, winding road winds spectacularly between steep rock faces, combining a challenging ride with impressive scenery. The asphalt is well-ridable, but you should expect tight bends, changing light, and heavy traffic—so it's best to ride in the early morning or late afternoon. A quick stop at the viewpoints is worthwhile to experience the magnificent views down into the gorge.

Madesimo is a renowned ski resort located in the upper Valchiavenna valley, in the province of Sondrio, just a few kilometers from the Swiss border. Nestled in the Rhaetian Alps at approximately 1,550 meters above sea level, it is one of Lombardy's most popular mountain destinations. During the winter, Madesimo transforms into a snow sports paradise, with over 40 kilometers of slopes extending up to Pizzo Groppera, at an altitude of 3,000 meters. The ski area offers trails suitable for both beginners and experienced skiers. In summer, the resort reveals its greenest and wildest side, becoming an ideal starting point for hiking and biking along Alpine trails. Visitors can explore the picturesque Lake Montespluga or try their hand at the area's trails. The quaint village still retains the authentic atmosphere of a small mountain village, with its typical stone and wood houses. Madesimo thus represents a perfect destination for those seeking genuine contact with Alpine nature, far from the mass tourism of the large ski resorts.

This small Alpine valley encompasses four hamlets in the municipality of Campodolcino: Starleggia, Cà De Luc, Splughetta, and San Sisto, surrounded by 11 mountain pastures, nestled in a splendid landscape stretching between 1,200 and 3,013 meters above sea level. Today, the hamlets are only partially used during the summer months, despite having been permanently inhabited until 1985. They are characterized by numerous small stone and/or wooden buildings (carden), all covered with typical stone slabs (piote). There are also some very interesting ancient buildings, such as the bell tower (built on a Roman-era structure), the rectory (12th century), and the Church of San Sisto (16th century).

The bike path mostly runs close to the lakeshore. On hot days, be sure to stop and stretch your feet!

Driving through these tunnels is a real highlight, but lights and a safety vest are recommended, as the tunnels are not lit!

51 switchbacks down into the valley. All numbered! It's simply a joy. But be careful in the unlit tunnels and galleries.

Beyond specific points, the undisturbed natural beauty, clean air, and quiet solitude are major attractions for cyclists seeking a serene experience.
