If you have a bit of spare time and you’re willing to travel 25 miles, take a look at Idar-Oberstein. This popular place boasts loads of things to keep you occupied. German Gemstone Museum, Crag Church and Bosselstein Castle alone make the drive out here worthwhile. The locals will also probably point you in the direction of Trier, 25 miles away. If you only have time for one attraction here, let it be Porta Nigra. (But we’d also highly recommend Arena Trier and Cathedral of Trier.)
