Long and challenging hike, leads you through some of the astonishing views and features that you can enjoy here in Luxembourg. I parked in Berdorf, at the beginning point of the famous E1 trail as the car park is bigger, free and shaded. You will walk mostly through woods, so it's perfect during hot weather. Plenty of seats and tables are displayed for picnic fans. You will also walk through the ancient city on Echternach, where several shops and restaurants are at your disposal for a break. Here, the signposts are a bit difficult to find, but you can follow the map on this app and you won't get lost. What else I can say: enjoy!!!
