On this first stage along La Voie Bleue in France, leave Sierck-les-Bains and its château built for the Dukes of Lorraine by following the meandering Moselle. Towards Contz-les-Bains, at a bend in the river, vine-covered slopes suddenly appear.
The cycle route continues beside the waterway, crossing typical Lorraine villages. The inauguration of the extra-wide lock at Kœnigsmacker in 1956 enabled riverboats from the Rhine Basin to transfer to the Moselle. Reaching Thionville, Basse-Ham Base Nautique, a boating and water-sports centre set in green surrounds, provides cyclists, campers and sailors with all the facilities they could need.
