The main road from Val Luzzone runs down to the village of Olivone (Romansch Uorscha, 893 m/2,930ft), a summer holiday resort beautifully situated at the junction of two arms of the Brenno under the massive pyramid of Sosto (2,221 m/7,278ft), surrounded by fruit trees. It has a fine old house, still inhabited, the Casa Cesare Bolla (ca. 1500),
once the residence of the governor, and an interesting local museum (opening hours given). Beyond Olivone the road to Biasca winds its way down the fertile Val Blénio, on the left bank of the Brenno, to the valley floor.
