There are some industries in the lower towns of Varallo, Borgosesia, Quarona and Serravalle. These are mainly the textile industry and precision engineering companies. Agriculture is also practised here; the wine from Gattinara, which also bears this name, is well known. The higher areas live mainly off of handicrafts and tourism, with both mountain hikers in summer and skiers in winter being addressed. Several stages of the 55-day long-distance hiking trail Grande Traversata delle Alpi run along the north side of the valley. The area around Alagna is developed with lifts, mountain huts and slopes for summer and winter sports.[1]
