One of the best-known ridge routes in the Eastern Alps is the Jubilee Ridge, which runs eastwards from the Zugspitze to the Hochblassen () and crosses the Inner (), Middle () and Outer Höllentalspitze () as well as the Vollkarspitze (). Along the way the route branches off towards Grießkarscharte () and to the Alpspitze (). Between 1909 and 1915 the ridge was partially secured with wire cables by the German Alpine Club section at Munich. Originally the route was called the Jubilee Way (Jubiläumsweg), but after a tragic rescue attempt in 1979 the rather erroneous and misleading term, which suggested it was just a normal trail, was replaced by the name Jubiläumsgrat, a Grat being a sharp ridge.
