The direct route
Ascent from the west
Waxriessteig, Trail No. 478
Around 3 hours walking time. Steep terrain, for experienced mountain hikers only. Parking available either at the starting point or at the Predigtstuhlbahn station. Parking is free in conjunction with a one-way or return ticket for the Predigtstuhlbahn.
The ascent is steep and narrow, but takes you up very quickly. After only a short time, you have the Saalachsee at your feet and can enjoy a marvellous view of the Chiemgau and Tyrolean Alps.
