If you’ve got a campervan, head over to the country next door. Prague, the capital of Czech Republic, is only a few hours of driving but you might as well be in a different world. Virtually untouched during WWII, Prague is awash with colorful Gothic, Renaissance, and Baroque architecture and plenty of historical monuments to boot. The castle and Wenceslas Square are two must-sees.
Don’t leave town without checking out the beer gardens or taking a food tour around town.

One of the best things about being based in a central city like Berlin is the fact that you can explore so many diverse places just within a day trip or weekend visit, and it’s perfectly safe to do so.
