Here are all the sections that I toured on, on one map. Click on the markers to get to the description of the tour.
It was cooler on the water. But I had to face a bit of wind. So, it took about 4 hours.
Griebnitzsee - Glienicke Brücke - Pfaueninsel - Wannsee Forum
Glienicke Brücke
Spontaneous bike tour with rain, hail and sun on the Thursday of Ascension.
Somewhere in Grunewald
A relatively demanding round trip past the further up and past a river (Font del Bac dels Monjos) at about 1300 m.
