The Gran Sasso is a mountain chain comprising the Corno Grande, Corno Piccolo and, separated by the Val Malone, the Pizzo d'Intermesoli.
The adjacent area to the immediate south is included in this area.
The area offers walks, via ferrata, scrambles, climbs, winter climbs and a ski area.
The Cicerone guide listed below is out of print, later guides to the region cover only walking. Italian guidebooks must undoubtedly exist.
