The best way to explore the area is of course by bicycle. You can cover a lot of distance in a relatively short time and enjoy all the beauty that the Ardennes have to offer. You can bring your own bike, or you can rent one: at Adventure Valley you can rent city bikes and mountain bikes, including a helmet. They also rent electric models, which can be very useful in the hilly nature. If you want, you can even cycle under the guidance of a guide on certain days.
If you prefer to go it alone, Adventure Valley can also help you with mapped out cycling and mountain biking routes. You can also follow one of the signposted routes such as La Route Champêtre or La Route des Tiges, or you can visit the Tourist Office for cycling maps.
