Make sure you have plenty of gas in the tank, because Nantes is worth a detour. Located 25 miles from Plessé, it has some wonderful attractions, such as Chateau of the Dukes of Brittany and Nantes Cathedral. Get set to start racking up those miles, because Le Chorus Exhibition Centre and Musee de La Cohue are also worth a road trip. You’ll discover these fine sights in Vannes, 40 miles away.
