Be sure to have enough gas in the tank, because Nantes is worth making a detour for. Located 30 miles from Tharon-Plage, it offers up some fantastic attractions, such as Chateau of the Dukes of Brittany and Nantes Cathedral. Get ready to clock up those miles, because Le Chorus Exhibition Centre and Musee de La Cohue are also worth a road trip. You’ll find these popular attractions in Vannes, 45 miles away.
