I got this tour from the HarzApp, which supports OutdoorActive, and copied it from there to Komoot. Today's tour was really fun.🚵🏻‍♂️😎 Right in the first third, there's the awesome descent to Wildemann. It's not easy, but the adrenaline rush is there.😝 Otherwise, you'll be rewarded again and again with fantastic views. With forest highways and single trails, uphill ↗️ and downhill ↘️, it's got everything.😊 Have a great time! Your emergency solution 😎🤟🏻

Short break in the beautiful Harz in Hahnenklee: the weather means well, so let's go on the mtb. First up to Hahnenklee's local mountain "Bocksberg" past ponds that belong to the water management of the Harz Mountains, on beautiful forest paths. Via Clausthal-Zellerfeld to Wildemann and from there a well-developed road with many information boards about leaves and conifers to the Grombacher pond and waterfall.
