July 24, 2022,Burg Blankenberg – Aussicht ins Siegtal Runde von Merten (Sieg)

Today it was supposed to be a short, easy tour. With the temperature, however, it should also be more in the shade. Unfortunately, this tour had a lot of sunny sections. First we went along the Sieg, past many paddocks. The path was only partially shaded. However, the path to the town of Blankenberg was very flat and easy to …

On Sunday I wanted to do a medium-sized lap at Blankenberg on the Sieg. Then it got shorter because I talked to people so much. First in the herb garden at the castle with two women from the circle of friends, see burggarten-blankenberg.de, then in the city of Blankenberg, there was the Regionale-2025 information day, see regionale2025. de/ .
And …

Komoot said that I should eat outside this week and get the full adventure enjoyment with a snack stop. What wouldn't you do for your health (and for Komoot). Of the many tours offered to me, I chose the one along the Sieg with the route through the town of Blankenberg, because it was a long time ago that I …

July 22, 2024,Runde von Blankenberg (Sieg)

To start the week, a short, relaxing hike around Blankenberg. It was so quiet along the entire route: you could enjoy the birdsong and the sound of the water.
The paths are quite varied: asphalt, gravel, but also meadows and forest paths.
