Located on the Rhône River, Avignon is the city to which the Popes fled when leaving the corruption of Rome in the 14th century. The palace they built, 'Le Palais des Papes,' is a breathtaking must see. After touring this majestic Gothic structure, be sure to hike the Parc de Rochers des Doms for a panoramic view of Avignon, the Rhône River Valley, and the St. Bénezet Bridge.
