The Nock Mountains may be divided into eight subgroups. South of Bad Kleinkirchheim are the stocks of the Mirnock massif ( m (AA)) with a significant topographic prominence of 1,343 m, the Wöllaner Nock ( m (AA)) and the Gerlitzen ( m (AA)) high above Lake Ossiach. The central region of the Nock Mountains is formed by the Millstätter Alpe ( m (AA)) and the Rosennock ( m (AA)), the highest summit in Carinthia. In the north are the stocks of the Schwarzwand ( m (AA)), the Königstuhl ( m (AA)) in Salzburg, which is also a tripoint, and the Eisenhut ( m (AA)).
