Pizzo di Claro, Mountain summit in Grisons and Ticino, Switzerland

Pizzo di Claro, also called Visagno, has two summits: the main north peak at 2,727 m and a south peak 7 m lower, joined by a 150 m crest. Its northwest face forms a large trapezoid visible across the Leventina valley. The mountain is mainly granitic gneiss, with amphibolite and eclogite near the top.

The summit marks the border between Ticino and Graubünden. The Capanna Brogoldone, a mountain hut at 1,910 m, was built to support hikers on the two-day crossing from Lumino via Monti di Saurù. The monastery of Santa Maria Assunta in Claro, founded in 1490, lies on a multi-day circular route around the mountain's base.

The poet Giorgio Orelli mentions the mountain in his poem "Dio vuole ch'è sabato". In October the Claro-Pizzo uphill race follows the trail from Claro to the south summit, covering 9.2 km and 2,500 m of ascent with about 200 participants each year.

The best climbing season runs from June to September when trails are free from snow and stable. Sturdy footwear and water are essential, as the ascent involves demanding terrain and some exposed sections.

The Claro-Pizzo uphill race has been held every October since 1998 on the trail from Claro to the south summit: 9.2 km with 2,500 m of vertical gain, around 200 participants each year. The south summit, 7 m lower than the main north summit, carries the summit cross and looks over Bellinzona and the Riviera.
