Discover the delights of nearby Trier. What’s 25 miles when you have your own rental car? The road trip there is half the fun! Porta Nigra, Arena Trier and Cathedral of Trier alone make the drive out worthwhile. Located 25 miles away, Idar-Oberstein is another popular tourist destination. If you visit, be sure to check out German Gemstone Museum, Crag Church and Bosselstein Castle.
