About Chironico

One of the largest bouldering venues in Europe — over 2100 problems across 37 sectors on the wooded hillside above Chironico village in Valle Leventina, spanning altitudes from ~800m up past 1200m. The rock is compact Swiss granitic gneiss with a rough, high-friction texture. Best autumn to spring for friction; winter is prime for the hardest projects if the snow stays off. Impermeable gneiss dries quickly after rain.

Region: Ticino — Bouldering
Rock type: Gneiss
Aspect: mixed-facing
Altitude: 900m
Exposure: medium
Seepage: low
