In the south the Noric Alps comprise the Klagenfurt Basin with the historic centres of Zollfeld and Magdalensberg. The mountainside is characterised by transhumance ("Alm") agriculture and was also a mining area, still for magnesite in the area of Radenthein. Today the region largely depends on tourism, in winter around the ski aras of Bad Kleinkirchheim, Krems, at Katschberg, Turracher Höhe and Klippitztörl, in summer around several picturesque Carinthian lakes like Wörthersee, Lake Millstatt or Lake Ossiach. The Nock Mountain National Park, accessible via the "Nockalmstraße" scenic road, is a protected landscape according to IUCN V category.
