The Wendelstein is a 1,838-metre (6,030-foot) high mountain in the Bavarian Alps in South Germany. It belongs to the so-called Mangfall Mountains, the eastern part of the Bavarian Pre-Alps. It is the highest peak in the Wendelstein massif. Due to its exposed location it has a very good view over the Bavarian Alpine Foreland and is unmistakable for miles around. It lies between the valleys of the Leitzach and Inn and is accessible via the Wendelstein Cable Car and the Wendelstein Rack Railway. On its northern foothills rises the Jenbach, which becomes the Kalten on its way to the River Mangfall.
Local valley settlements include Bayrischzell, Brannenburg (rack railway) and Osterhofen (cable car).
