In Hammer Bakker, north of Aalborg, there are three different mountain bike trails, but also plenty of opportunities to cycle on trails and gravel roads, there is something for everyone.
Mountain bike trail "the long" (moderate) is approx. 10 kilometers and the “short” (difficult) of approx. 3 kilometers with approx. 450 altitude meters. The "long" and "the short" start in the same place and the first kilometer is the same part on both tracks. There is also the blue family trail (light), which is lighter and shorter. The mountain bike trails in most places have the opportunity to choose a difficult and an easier road, which means that riders with different levels can go on a trip together.
