Make sure you have enough gas in the tank, because Nantes is well worth a detour. Located 40 miles from Le Boupère, it has some terrific attractions, such as Chateau of the Dukes of Brittany and Nantes Cathedral. La Rochelle, 45 miles away, is another road-trip destination that’s worth the journey. Visit Tour St. Nicolas and La Rochelle Hotel de Ville, two top-notch attractions in the area.
