Starting in the Rißtal this tours leads first to the Plumsjoch cabin. From there you have several choices. Depending on how good in shape you are you can climb the Bettlerkarspitze and then go back to where you started or you can walk across the Mondscheinspitze and Pletzach Valley to Pertisau. Since I came to the Gernalm around noon, I decided to go for a second ascent and walked over Guetenbergalm to Pertisau. To get to the starting point at the Hagelhütte you can use the Bergsteigerbus from Lenggries and take another bus from the Achensee back to the Tegernsee. You will be rewarded with great panoramic views and a few good places to take a rest and get a snack.
