The Rhineland-Palatinate has several interesting cities to use as a base for your visit, such as Mainz, Worms or Koblenz. Spend a couple of days exploring their historic hearts before heading out in your car rental to explore the area's beautiful countryside. If you enjoy history drive through the Hunsrück district with its Roman and Celtic remains or head to the hills of Taunus and Westerwald in your car hire and spend some time hiking in the countryside. If you're a wine lover take a cruise in your car rental from the Rhineland-Palatinate through the Rhenish Hesse area and visit local vineyards, as well as stopping off in little villages with their distinctively Mediterranean appearance. Another good day out can be had in the Rhineland-Palatinate Forest, look out for some of its fifty or so castles as you drive.
