The Blenio Valley in northern Ticino extends from the Lukmanier Pass (1914 meters above sea level) down the valley to Biasca. In summer, hikers encounter well preserved old villages and art treasures on the valley trail from Biasca via Acquarossa to Olivone. The valley also offers a broad spectrum of cultural offerings, including a large number of museums and churches.
Located at the foot of the pyramid-shaped Sosto mountain (2221 meters), Olivone is the starting point for excursions and hiking tours to the impressive Greina Plateau, to the untouched Val di Campo or to the Luzzone Reservoir Lake.
