Aschaffenburg Cruises, Germany

This Bavarian town is peppered with landmarks that look like they’ve been ferried in from around the world. There’s a sprawling park inspired by British landscaping, and a replica of a Roman villa copied from the Pompeii excavations. Then there’s Theatreplatz Square, which is lined with olive and lemon trees – like a scene straight from the Mediterranean. The square’s also home to one of Europe's largest sundials, so have the camera handy. Other must-sees include the Gothic Basilica of St Peter and Alexander, and Johannisburg Palace – a red sandstone fortress that towers over the River Main. Once you’re done with the big-hitting tourist spots, relax with a local Bavarian beer in the old town. This labyrinth of narrow alleys is freckled with German bars and quaint restaurants inside pretty half-timbered buildings.
