About this event

The 11th edition of this national street boulder festival sets around fifty problems on the medieval buildings of San Gemini. Climbers log their ascents in an app, the best six men and women climb a public final on an artificial wall, and the weekend adds aerial acrobatics, yoga, urban trekking, kids' activities and a Saturday concert.
