Typically completed as an 11 Stage/Day Hiking trail through the "Wild Heart of Austria", the route travels through three internationally recognised protected wilderness areas (Kalkalpen Natonal Park, Gesäuse National Park and the Dürrenstein Wilderness Area) with parts of the trail belonging to the UNESCO World Heritage Site Beech Forests.

This route is based on the Arizona 20-20 Challenge. Arizona is a state with incredible diversity but peakbagging lists in Arizona have been problematic. Many of the highest peaks are private or closed for various reasons.
