The Stelvio National Park or Nationalpark Stilfser Joch, established in 1935, is one of the oldest Italian natural parks and also the largest. It was created with the aim of protecting the flora, fauna and the beauty of the landscape of the Ortles-Cevedale mountain group, and to promote the development of sustainable tourism in the Alpine valleys of Lombardy, Trentino and South Tyrol. As far as the Lombardy sector is concerned, the territory of the park includes the northern areas of the municipalities of Livigno and Valdidentro, always bordering the municipality of Bormio to the north and almost entirely incorporating the municipality of Valfurva.
The Valle dei Forni, entirely included in the park and ideal for mountain biking or on foot, takes its name from the glacier of the same name, surrounded by a series of peaks called "the thirteen peaks". The glacier is one of the largest in Italy, although in the last century its length has increased from 6 to 3.5 km.
The Valle del Gavia, as wild as it is fascinating, belongs to the group of great climbs of the Giro d'Italia. The Gavia Pass (2,621 m asl) connects the upper Valtellina to the upper Valle Camonica in the province of Brescia.
The Val Zebru', still in the municipality of Valfurva, can be reached from Bormio through the village of Madonna dei Monti. The valley winds for about 12 km and can only be traveled on foot or by MTB, and is characterized by a massive presence of ungulates. It is not difficult to come across herds of ibex, deer or chamois here.
The Valle Alpisella and the Val Trela develop starting from the Fraele valley, the starting point for the tour of the Cancano, and offer an alternative route to connect with Livigno.
Finally, the Valle del Gallo, the most pristine in the park, extends into Swiss territory.
