Boasting Medieval fortresses, Roman aqueducts, Mediterranean coastline, endless vineyards and expansive national parks, a visitor could spend a lifetime exploring sunny Languedoc-Rousillon. Sitting on the geographic divide between the Iberian peninsula and mainland Europe, the regions towns and cities, including beautiful Carcassonne, Nimes and Montpellier, are connected by paths both ancient and new. Hike Via Domitia, a Roman road, or rent a barge for a trip down the Canal du Midi.
