Be sure to have a full tank of gas, because Grenoble is worth a detour. Situated 40 miles from Champoleon, it offers up some terrific attractions, such as Museum of Grenoble and Fort de la Bastille. Chambery is another road-trip destination to consider. It’s situated just 60 miles away. If you make the trip here, Chateau de Chambery and Carre Curial should be on your must-do list.
