Make sure you have a full tank of gas, because Nantes is worth a detour. Situated 40 miles from Givrand, it’s home to a few fabulous attractions, such as Chateau of the Dukes of Brittany and Nantes Cathedral. Get ready to start racking up those miles, because Tour St. Nicolas and La Rochelle Hotel de Ville are also a rewarding road trip. You’ll find these well-known sights in La Rochelle, 50 miles away.
