Strasbourg, capital of the Grand Est region and once part of Alsace, straddles the French-German border, its river marking the divide. A guided tour reveals the storybook charm of the Old Town, with timber-framed houses, winding alleys and the flower-lined canals of Petite France. Marvel at the soaring Gothic cathedral, then journey on to Obernai, a postcard-perfect Alsatian town where we enjoy more guided insights and free time to explore its medieval streets, market squares and local delicacies.
