In a varied landscape context, between watercourses and broadleaf forests, the route crosses fields, apple orchards and vineyards, chestnut groves and ancient terraces. But it is the castles, towers, and churches that follow one another along the way that give a distinctive character to this itinerary. Starting from the Tirano Bus Station, you first gently climb along the valley floor cycle path, with slopes becoming steeper near the Vione tower (short S3 uphill section).
Between dirt roads and fast single-tracks, the ride continues to Grosio, where the Visconti Castle, the Rock Engraving Park, and the San Faustino Castle offer great opportunities for a refreshing break. Rest areas are also present along the route, for those wanting to explore the territory from a culinary point of view. Upon reaching the turnaround point, you move to the left bank of the Adda river, to face ups and downs on fun trails up to the Pedenale tower and Bellaguarda Castle. Then you continue downhill, encountering a short technical section (S3) easily managed by pushing the bike.
Then you climb towards the Sernio tower and, after a long traverse through the forest, you reach the rewarding final descent (S3) that leads back to Tirano passing by the Santa Maria Castle, called Castellaccio. Thanks to the favorable exposure and the moderate elevations reached (max 720 m), the Trail is suitable for all seasons, except perhaps for the coldest months and the central hours of hot summer days. The route is fully supported by vertical signage (red arrows), information boards, and horizontal signage with white and red trail marker flags, and requires adequate technical riding skills (medium difficulty S1).
Clockwise direction is recommended.
