An itinerary to discover history in modern times and the traces of ancient trades.

Starting from Albaredo along the ancient via Priula, built in the second half of the 16th century to connect Bergamo to Morbegno, facilitating trade between the Venetian Republic and the Grisons, the hike touches some places that revive the ancient peasant atmosphere. This is the Ecomuseum tour, an open-air museum with informative signs along the way. Interesting are the tollhouses for milk storage, the remains of the manufactures of the past, with sawmills and the "puiat," the stations for producing charcoal, or the old smelting furnaces for processing iron mined at high altitudes.

The itinerary begins at the Park Gate of Albaredo (900 m), near the parish church. Climbing to the top of the hamlet, take the trail just beyond the dairy building. 2 kilometers further on you intersect the road leading to Passo San Marco, and take the ancient Strada Priula: the road, according to a legend widespread in the area, was once haunted by witches.

Continue in the direction of the small church dedicated to Madonna delle Grazie (1150 m) built in 1732, from which the view is admirable. After a short descent you cross the Piazza and Pedena streams: the latter once fed a sawmill, which was not modernized until 1935 with the use of electricity.

Beyond the bridge you reach an old charcoal kiln, and continuing on you arrive at the milkhouse: Bitto cheese, yesterday as today, represents the soul of the area. When you reach the houses of Dosso Chierico (1219 m) you come to a fork in the road: the hike can continue along the Strada Priula to Passo San Marco, or, as in this case, you take the path to the right that descends to the heart of the valley.

Avoiding two detours to the right, one stops at the smelting furnaces (1180 m) in the Orta Woods, another interesting point of the Ecomuseum. The last stop, just aboveAlpe Vesenda Bassa (1350 m) in the village of Bema, is the famous Vesenda fir, a centuries-old tree (estimated 350 years old). At this point, on the same route as the outward journey, the return to Albaredo begins.
