Located in the northernmost part of Piedmont, touching the Swiss border with its horn, the Ossola Valley extends along the ridge of the Pennine and Lepontine Alps which culminate respectively with Mount Rosa (4634 m) and Mount Leone (3552 m).
The Toce River remains the backbone around which the Valley develops; it’s spring is in Alta Formazza and it flows into the 8 valleys from the Toce waterfall, located at 1675 meters above sea level with a plunge of 145 meters, then continuing along its entire 83 km course that eventually leads it into Lake Maggiore.
The Ossola Valley is made up of eight main valleys: Val'Anzasca, Antrona, Bognanco, Divedro, Formazza, Antigorio, Vigezzo and the Isorno Valley.
The whole mountainous territory is historically characterized by a mountaineering based economy which was born in the mid-nineteenth century and acts as the principal source of development and income in the area.
Alpine lakes and vast woods enrich the wonderful heterogeneous territory of the Ossola Valley, which draws the interest of thousands of nature lovers every year with its countless natural and gastronomic attractions.
While exploring these valleys, one comes across 4 natural parks which best demonstrate the rich variety of this territory:
- The Val Grande National Park, renown as the wildest area in the entire Alpine arc;
- Alpe Veglia and Alpe Devero Natural Park;
- The Upper Antrona Valley Natural Park;
- The Special Natural Reserve of Sacro Monte Calvario.
