Make sure you have enough gas in the tank, because Grenoble is well worth a detour. Located 40 miles from Pelvoux, it offers some wonderful attractions, such as Museum of Grenoble and Fort de la Bastille. Chambery, 55 miles away, is another road-trip destination that’s worth the drive. Stop by Chateau de Chambery and Carre Curial, two must-see sights in the area.
