Since the nineties, the mountain bike course in Overijse and Huldenberg has been a well-known route. At the time, it was one of the first permanent mountain bike routes in Flanders. After many years of service, there was a need for renewal of the outdated route.

The renewed mountain bike route "The 2 Valleys" in the territory of Overijse and Huldenberg features three new mountain bike loops:

• the red loop of 23 km with 13 km of unpaved trails starting from Overijse (Begijnhof)
• the blue loop of 22 km with 13 km of unpaved trails starting from Sint-Agatha-Rode (Church)
• the green loop of 12 km with 8 km of unpaved trails starting from Terlanen (Church Square)

For experienced mountain bikers, the new red, blue, and green loops can also be combined into a total route of 57 km. The renewed route is in total a mere 24 km longer than the old route and includes more than 34 km of unpaved paths.

Characteristic of a route in the Grape Region is that there are in total more than 700 altitude meters, with challenging slopes and technical singletracks, making it a real playground for mountain bikers from the wider area.
