Cologne Cruises, Germany

Cologne City Tour with Cathedral

This three-hour tour is the same as the Cologne City Tour, and includes the added bonus of a visit to the city's famous cathedral. The foundations of the twin-spired cathedral date back to the 1200s, and the architecture inside is jaw-dropping – you'll get to see both on this guided tour. You'll also have the chance to pay to climb the 533 steps to the top of the south tower, where you'll be rewarded with panoramic views across all of Cologne. The cathedral's treasury is also worth a look – you can inspect its 4th-century gold and silver, for a little bit extra.
