Today we went to the Karwendelhaus in the best weather. On the way there was a lot going on due to the good weather. The higher it went, the quieter it got. As a reward for the effort, there was a fantastic mountain view and a never-ending descent back into the valley.

Tour No. 3
Pedal and enjoy...both the panorama and the Kaiserschmarrn (sweet pancakes). Through the Karwendel Valley, surrounded by huge rock faces on both sides...fantastically beautiful.

I fulfilled my wish to go up the Karwendelhaus again after a long absence (I don't live here either). It's not as beautiful as the Isar source, but it's also impressive because the valley is wider. I was surprised why they put up a barrier and closed it, making it almost impossible to get past. Luckily, it was open on …
