Be sure to have a full tank of gas, because Avignon is well worth a detour. Located 30 miles from Saint-Marcel-d’Aredeche, it offers up some fantastic attractions, such as Palais des Papes and Place de l’Horloge. Get ready to start clocking up those miles, because Maison Carree and Nîmes Museum of Natural History and Prehistory are also a rewarding day trip. You’ll find these popular attractions in Nîmes, 35 miles away.
