The beauty of renting a car is that you can go where you want, when you want. Make full use of your freedom by exploring all there is on offer in Andernach. It’s just 16 miles away. Among your first stops here ought to be Laacher See, Namedyer Werth and Neuwied Castle. The locals will also likely point you in the direction of Neuwied, 19 miles away. If you can only see one thing here, let it be Sayn Castle. (But we’d also highly recommend Namedyer Werth and Neuwied Castle.)
