Around the Granestausee leads a very nice bike path, which always offers beautiful viewpoints on the lake. He also does not have too many vertical meters and should be easy to handle, even for beginners.

Last day in the Harz Mountains. It started cool and overcast. And it stayed that way. It started to rain lightly at the Innerste Reservoir, but it cooled down. A shame, since the past few days had been so summery.

One highlight was definitely the plug there (see photo!

Definitely a unique feature worldwide 😎.

Goodbye Harz!

... whoa, I had to go out with this weather 😊
First it was the circumnavigation of the Granetalsperre, then it continued with some steep climbs in the direction of Wolfshagen. From the Innerstetalsperre, and then back to the Grane.
So, everything is completely full of dust, now man & machine are being made pretty again 🤪.
I wish everyone …

First major dam circuit around the Innerste and Grane. There was still a lot of riding on the trails, but the temperatures were very good. A little less wind would have been nice, but it was still a lot of fun 😊

May 2, 2026,Wasser, Wald und Wiese: Langelsheim - Wolfshäger Panoramarunde - Granestausee

On the first May weekend, we went by bike into the forests between Langelsheim and Wolfshagen. At the beginning, we briefly rode along the refreshingly babbling Innerste.

On the Wolfshäger Rundweg, numerous great panoramas over the meadows, pastures, and forests offered themselves – I always find it amazing that we have such landscapes right on our doorstep (and that you …
