The joy of having your own ride is that you can travel where you want, when you want. Make the most of your newfound freedom by discovering all that there is to do in Mainz. It’s just 20 miles away. Mainz Cathedral, Gutenberg Museum and Mewa Arena alone justify the drive out here. The locals will also probably point you toward Wiesbaden, 25 miles away. If you only have time for one thing here, make sure it’s Mainz Cathedral. (But we’d also recommend Gutenberg Museum and Nerobergbahn.)
