Upper Austria slopes from the densely wooded granite and gneiss highlands (Plöckenstein, 1,379 m ASL) in the north, which are part of the so-called Bohemian Mass, to the Danube in the south (approx. 250 m ASL). To the south of the Danube the foothills of the Alps spread out forming a flat or slightly hilly zone of molasse and reaching 801 m ASL at Göblberg in the Hausruck. Further south again a 10 to 15 km wide band of flysch (mainly sandstone) follows which is characterised by soft ridges and hilltops and heights of up to approx. 1,000 m (Pernecker Kogel, 1,080 m ASL). In the very south of this region the Northern Limestone Alps run from Hoher Dachstein (2,995 m ASL) via Totes Gebirge, Höllengebirge, Traunstein and Warscheneck to Sengsengebirge. The pre- and high alpine character of this area offers a lot of summits for activators, especially in higher reaches. Linz (third largest city in Austria, approx. 186,000 inhabitants) is the capital of Upper Austria. Linz is a modern commercial and industrial town with a beautiful historic center. Due to its central position and the good transport connection Linz is an ideal starting point for expeditions to all parts of the region.
