Brittany's dramatic 750-mile coastline traces a rugged hem against the chilly Atlantic. Attractions such as St-Malo's 1689 Fort National, the prehistoric ruins and striking beauty of Gavrinish Island and Brest's Oceanopolis aquarium cling to the rocky shoreline of France's most northwestern province. Nantes, Rennes and Brest are the largest cities. Rennes is just two hours from Paris by TGV. Breton and Gallo, the ancient languages of this Celtic province, are still spoken in pockets throughout the area.

Situated at the foot of the western Pyrenees near the French border, Spain's Basque country comprises three provinces: Guipúzcoa and the popular beachfront capital of San Sebastian; Viscaya, where capital Bilbao houses the jaw-dropping Gehry-designed Guggenheim Museum; and Alava, whose capital Vitoria teems with medieval architecture. Running with the bulls at Pamplona and drinking rioja from local wineries add to the region's exotic romanticism. Travel in early summer and autumn to avoid the crowds.
