North Shore of the Oleftalsperre

Highlight • Lake

The Oleftalsperre protects the surrounding communities from flooding and is used to obtain drinking water. It is very impressive to cycle along this huge reservoir.

Old Water Crane for Steam Locomotives (Buchholz)

Highlight • Monument

A relic from days gone by to look at. But information boards along the route also tell of these times. In the meantime, the station has been a bit embellished and there is also a nice break bench.

Water pump station for steam locomotives on RAVeL L45A

Highlight • Monument

Coming from Germany, it is always uphill, but with an e-bike it is very moderate and problem-free.

Highlight • Cycleway

The Vennquerbahn cycle path is very well developed and very easy to drive on. Smooth asphalt and plenty of opportunities to take a break.

September 26, 2023,Rundtour Hellenthal über Oleftalsperre - Hohes Venn - Vennquerbahn - Kronenburg II

The tour was so great in June that we did it again today with a slightly larger (and this time female) group.
Except for a few kilometers, the entire route is on car-free paths and can be ridden without any problems, even with normal trekking bikes.
The rapid descent from Udenbreth into the Prether Bachtal is particularly fun to drive. …

June 1, 2023,Rundtour ab Hellenthal über Oleftalsperre - Hohes Venn - Vennquerbahn - Kronenburg

After a trip to the Sauerland dam region, it was the turn of the Eifel again today.
In fantastic biking weather, a tour to enjoy the Eifel landscapes on both sides of the German-Belgian border area with start and finish at the Oleftalsperre.
The pictures of the tour speak for themselves; a comment is therefore probably completely obsolete.
Warmly recommended …

Beautiful tour!!!
This tour was recommended by Wolli; it's almost entirely forest and almost car-free, easy to ride, and I can recommend it.
The highlight: Kronenburg Castle, quite steep 😉 and Kronenburger Lake 👍 very beautiful. I didn't need the spare battery 😉
