Be sure to have a full tank of gas, because Grenoble is well worth a detour. Situated 20 miles from Saint-Andeol, it offers some fantastic attractions, such as Museum of Grenoble and Fort de la Bastille. Nothing says living large like a road trip does, so keep on cruising to Chambery. It’s 45 miles away and also features a few worthwhile sights, such as Chateau de Chambery and Carre Curial.
