Wendelstein is a mountain in the Bavarian Alps in South Germany. It is part of the Mangfall Mountains, the eastern part of the Bavarian Pre-Alps, and is the highest peak in the Wendelstein massif. 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 and Osterhofen.
