I’m in the Adamello Brenta Nature Park, the largest protected area of the Trentino region at Italy’s northeasterly reaches. Spilling into the Alps on the border with Lombardy, the Unesco-listed geopark is shaped by two geologically diverse mountain ranges: the limestone Brenta Dolomites, with their rugged towers and jagged peaks, and the granitic Adamello-Presanella group, home to Italy’s largest glacier. The result is a geologically unique landscape, taking in dense larch and pine forests, verdant pastures, razor peaks, glaciers and plunging waterfalls.
