This Michelin Green Guide explores northeastern France from the open horizons of Champagne to the stony cliffs of the Meuse valley and the thick forests of Ardennes and Argonne. The blue line of the Vosges mountains rises between Lorraine and Alsace, where vineyards stretch from the foothills to the Rhine valley plain. Majestic Gothic cathedrals, half-timbered villages, mountain retreats, medieval castles, museums for every interest distinguish this historic land and cultural crossroads.
