The Belgian commune Viroinval is located in the province Namur, just at the French border. The valley of Viroinval stretches out over 8 picturesque villages such as Dourbes, Mazee and Vierves-Sur-Viroin. Together this forms the nature park Viroin-Hermeton which consists of 12.000 hectares of deciduous forest, the lake of 'Ry de du Rome' and the canyon 'Fondry des Chiens'.

The bikepacking weekend "Viroinval" lets you discover the beautiful nature in the Viroinval valley. You explore the area from a mountain bike. You take the necessary equipment, including the bivouac equipment and food, with you on the mountain bike. This way we can enjoy the peace, adventure and adventure together for a few days completely autonomously.

The bikepacking tour has a total length of approximately 90 km, spread over an evening and two days. You are self-sufficient in terms of food, drink, clothing and accommodation.
