About Brione Verzasca

The Val Verzasca bouldering venue — around 550 boulders across 19 sectors strung along the river and in the meadows and forest around Brione, plus the neighbouring Lavertezzo and Sonogno areas. Rock is compact granitic gneiss with a finely-grained, medium-friction surface — the harder classics (Amber 8B, and dozens of 8a+/8b) are the reason it earned a global reputation, but there are moderate problems everywhere. A formal bouldering access agreement is now in place — respect the marked areas and pad-line rules. Some boulders that sit in shallow hollows (e.g. Real Pamplemousse) hold condensation and dry more slowly than the open ones — worth checking before you drive.
