The Blenio Valley (Valle di Blenio) in northern Ticino extends from Biasca up to the Lukmanier Pass. On the valley path from Biasca via Acquarossa to Olivone one encounters well-preserved villages and art-historical treasures. The resort of Olivone at the foot of the Sosto (2221m) is the starting point for many excursions in summer. In addition to nature, the valley offers a wide range of cultural activities with numerous museums and churches.
