The Rovana valley is narrow and steeped in history; its far end is a delight. A long, winding road leads to Bosco Gurin, a well-known Walser village, the highest (1504 m) inhabited village in Ticino and the only place in the canton where German is spoken. It’s a popular hiking and skiing destination. Turning left halfway along the valley in Cerentino, you reach the Campo valley, great for scenic hiking and ski tours. The Bavona valley is home to 12 hamlets and takes you back in time. This fairytale world is home to traditional stone houses (rustici) from which smoke rises, large slabs of rock which served as shelter (splüi), huge boulders acting as hanging gardens for nature, colourful flower meadows, steep cliffs and waterfalls; with no electricity (except in San Carlo), the valley is inhabited in summer only. The waterfall in Foroglio is a particular attraction: a cascading natural spectacle and a real source of energy. The Lavizzara is the most inhabited of these side valleys. It’s where world-famous Peccia marble is quarried – the country’s sole source of this rock. Peccia is also home to the International Sculpture Centre, a mecca for artists from the world over.
