Gravel loop between Watten and Clairmarais

The ride

Roll out of Houlle and follow the La Houlle river before joining the L'Aa Canalisée. The route then leads through the Parc naturel régional des Caps et marais d'Opale, a nature reserve, and past the La Haute Meldyck river. Of the 60.0 km, part runs unpaved, and the loop brings you back to Houlle with 391 m of climbing in the legs.
