Introduction
Ticino is a bouldering region, not a single crag: Cresciano, Chironico and Brione (Valle Verzasca) each anchor their own valley, with further areas at Sobrio, Gottardo and beyond documented more thinly across our approved sources.
Across theCrag, UKClimbing, thetopo.com and Climb Europe, no two sources agree on a single region-wide problem count — estimates range from a curated "best of" selection of about 1,000 problems up to a full valley-by-valley database total over 13,000. We report per-area figures with attribution rather than one blended number.
