For this extension, plan in about 1.5 hours more time and some additional climbs. Instead of beginning the return leg at Brand, turn to the right and follow the Kaiserwinkl cycle touring route onto Buchberg and Durchholzen. At the Amberglift, turn off to the right and cycle along idyllic trails all the way to beautiful Lake Walchsee. Circling the lake marks the turning point of the route. At Seehotel Brunner, join the main road to the left. It's only a couple of hundred metres until you'll get back onto quieter roads in the centre of Walchsee. The route leads past the Schwemm Moorlands and the Golfclub Walchsee-Moarhof. Further in a western direction, cycle steadily downhill along the Staudinger stream. Not far now, and the extension route rejoins the tour "Enjoyment in the Untere Schranne" again.
