Luxembourg's mountain-bike loops
Luxembourg has a dense network of waymarked mountain-bike loops: national MTB tours, the RedRock trails on the former mining land of the south, and local circuits in the Éislek and the Mullerthal. Most are permanently signposted and start in villages you can reach by bus — free of charge nationwide.
This site presents the tours one by one: interactive map, distance, elevation profile, approximate riding time, GPX download and the bus stops on the route. Route data comes from OpenStreetMap, stop data from Luxembourg's official timetable feed.
