INFORMATION IMPORTANTE

Located in the east of Belgium, this route links the 7 communes of the province of Liège included in the EXTRATRAIL network (Spa, Stoumont, Jalhay, Stavelot, Theux, Trois-Ponts & Malmedy).

Designed for athletes who want to take on an intensive challenge, it is also great for trail runners and walkers who want to explore.

You are free to organise your journey by defining the daily distances and points where you will sleep, eat and refuel. However, the Tourist Information Offices in the towns and communes you come across will be able to offer advice and help with any reservations.

You are also free to design your route by selecting one or more sections of this extensive route and planning potential transfers by taxi or bus.
