Day one:
The hike starts at the top station of the Kaiserlift, as it is advisable to take the lift up in the morning. Over the Steinbergalmen you can still enjoy the wonderful view of the Koasa until after a short stretch you descend towards Bettlersteig and turn right towards Güttlersteig. This is where the part begins that requires a good surefootedness. The effort is worth it, on the Sonneck you can expect the best views over the peaks of the emperor and into the Inn valley.
Downhill again via the Güttlersteig to the Kaisertal to the Anton-Karg-Haus (Hinterbärenbad) or Hans-Berger-Haus. It is best to spend the night there, otherwise it can be very late.
