Scenic Mountain Road with Panoramic Views

Highlight • Viewpoint

Exactly what the Harz Hochstraße, for example, is unfortunately far too rare for: narrow, narrow, curvy. Absolutely recommended, especially downhill towards Altenau 😁

Siebetal Check 💪🏼 What a beautiful tour! Osterode and Herzberg won't be part of the poetry album, but Sieber and the climb through the forest will! There was a lot of humidity in the air in the Harz Mountains, and then brutally windy on the flat route home - but it was still beautiful 😍
