Sometimes you only have one single day to visit a city. And no matter what the reason for that may be (either you are leaving the next day or you just want to spend the rest of your holiday drinking beer) you can´t afford to lose any time. Here come some advices what to see in Copenhagen in one day.Start your tour near the city hall. It´s tower with 300 steps leads you to a platform with a nice view. But seriously: you can forget these steps, I´ve got a better view for you later on. Why were are actually here: Near the city hall starts the oldest and longest shopping street in Europe: Strøget… And you can´t miss this important part of history, don´t you? .Strøget finishes after 2 km at Amagertorv. For all of you, who already need a yummy-break (so to say for everybody) I would recommend Café Europa with it´s excelent fish dishes. This is the better view without stairs I promissed to show you: The Round Tower has a 206 meter long helical corridor leading you to the top with an expansive view over the whole city.At 12 a.m. you should be at Amalienborg, the home of the Danish royal family, to see the guard change. The special thing about Copenhagen is that you get really close to them (much closer than in London for example).In this building lives Queen Margrethe II. Sometimes she is observing the guard change from her window.After visiting Amalienborg you can walk about 10 minutes to Nyhavn, the most famous place in Copenhagen with many colourful houses. I could spend there hours watching people and eating! Look at my hard rock fries!Now you still have plenty of time to visit another places. We stopped by at the Designmuseum where we could admire about 200 Danish chairs and then we had a really informative tour in Christiansborg Slot, the former Royal home and now the seat of the Danish Parlament. Read here what we did at night and get here some ideas where to relax in Copenhagen.
