Billed as the largest street boulder event in Europe, the festival turns the medieval village of Serra San Quirico into a climbing playground, with a street boulder contest scored through an app and finals on Saturday night. Around it: climbing in the Gola della Rossa and Frasassi park, caving, trekking, yoga, slackline and acroyoga workshops, and talks with guests such as Angelika Rainer and Kim Ja-in.
