Cologne, a German city with 2000 years old history, leaves an impeccable impression on the mind of a curious traveller. The ruins of Roman Era, a beautiful river view, the third tallest cathedral in the world, museums, riverside restaurants and the centuries-old colourful buildings decked on the harbour of River Rhine; they all make this city a cultural hub of Western Europe. There are many interesting and best things to do in Cologne. I have enlisted a few of them which I explored during my day trip to Cologne from Frankfurt.
During my backpacking trip to Europe, I got a chance to opt for a one day trip to Cologne for Frankfurt. Definitely, just one day trip is not enough to experience this city of carnivals and varied cultures. However, you can make the best of your one day trip to Cologne provided that you start early.
