Jubiläumsgrat connects two famous mountains Zugspitze and Alpspitze from West to East. There are several peaks in the middle of the ridge: three Höllentalspitze and Vollkarspitze (2,618 m). The route is a high alpine tour and not a via ferrata route. In 2000/2001 winter and in autumn 2001 Vollkarspitze broken off in two rockfalls and fell into Matheisenkar. Since then the ascent to Vollkarspitze from West to East is very steep and slightly overhang is the key point of the whole ridge and is rated as via ferrata difficulty grade D. To do this ridge without cable car help, you need to be very very fit.
