The GR 17 is a 105 km long-distance trail in southern Belgium, running from Libramont to Anseremme. The route follows a varied and scenic line through the Ardennes, combining forest tracks, rolling farmland, technical single trails, and quiet rural roads. With a mix of runnable sections and punchy climbs, it offers a challenging yet flowing profile typical of the Belgian Ardennes.

De Aachener Gipfelsteig loopt door de mooiste gebieden rondom Aken. Afwisselende wegen en paden, weidse uitzichten en prachtige bossen en riviertjes nodigen je uit om ontdekt te worden. 

The start is at the main cross-country skiing parking lot at Forêt Montmorency and the finish is at Rang Saint-Julien (at the entry gate). You will travel through the Seigneurie de la Côte-de-Beaupré, also known as the Terres du Séminaire, along this route.

The trail is generally clear, except for two sections:

1. At approximately 2.5 km, you must cross a river.

2. Around 9 km, there is a very old suspension bridge that must be used. Please use caution in this area.

The remainder of the route follows a long gravel road.
