Mount Orsa is a mountain of almost 1000 meters on the Luganese pre-Alpine ridge, the third highest in Valceresio after Mount Piambello and Mount Pravello. 

From a historical point of view, it is certainly interesting due to the presence of the trenches of the Cadorna Line. 

The lanscape offered by this peakes, in addition to the interesting karst system of which they are composed (caving is also possible!), is ideal for sports loved by many: climbing (for example on the 'Sunset Cliffs' site), cycling and walking tours, skiing, snowboarding and cross-country skiing.
