A beautiful, leisurely, shady hike. Adequate at 32 degrees.

March 22, 2025,Felsenmeer im Erdtal – Felsenmeer Runde von Böhringen

A very beautiful hike in the Erdtal valley, amidst the snowdrop blossoms. The approximately 600m section to Schreckenfels is very narrow. A steep drop through the forest on the right side. With a dog leading the way and occasionally pulling, it's quite difficult. In dry weather, however, it's doable and varied.

There are new things …

Where do you go when it's 25 degrees in the morning? Exactly, in the shadows. Today went a little differently than usual.

Dodged the beekeeper and the buzzing bees respectfully.

October 8, 2022,🍁🍁🍄 Spontane Herbstrunde 🍂🍂🍄

Spontaneously decided to run together in the Erdtal.

Also beautiful in autumn, even if it was slightly slippery today. But sturdy shoes are a MUST there anyway, at least I think so.

➖ Schreckenfels, then on an unmarked path in the forest to
➖ Erdtal, further to
➖ Grosser Schrecke, after descending from there along the valley towards Schlattstall and just before the town up the forest path …
