Illuminated Christmas market hike
I propose you to join a hike in Metz (France, 65 kilometers from Luxembourg, less than 1 hour driving without traffic jams).
This 10 kilometers hike will take place in the city and will go through illuminated streets and the various Xmas market places downtown. The city is a unique mix of French and German architecture. Note that this is an IVV affiliated hike.
