Although the Kempen has a relatively flat landscape, you will also find a number of very challenging mountain biking routes that can appeal to both seasoned and beginner or young mountain bikers. There are swirling sand dunes and winding forest paths that contain treacherous turns. Even for those who are just starting out or looking for their first mountain biking adventure, there are nice routes. For example, in Kasterlee, you will find the blue route that starts at the parking lot near the Duineneind sports hall (Kasterlee). This route quickly becomes hilly, requiring some steering skills and gear shifting technique. This varied route soon treats you to some muddy sections to overcome.
