1. Take A Stroll around Tivoli Gardens If one is visiting Copenhagen in the summer when the temperatures are pleasant and the days long, checking out Tivoli Gardens is a must. Named after an Italian town, the garden is well manicured and has nightly events such as films or a play. There are at least ten hotels in near proximity to the gardens if you want to be staying close to this attraction.
2. Photograph Den Lille Havfrue
Located in the harbour, this little mermaid statue is world-famous. Constructed in recognition to the accomplishments of the equally world-famous fairy tales author, Hans Christian Andersen. The statue was an exhibition at the 2010 Shanghai World Exposition.
3. Visit museums on Wednesdays
On Wednesdays, entries to some Copenhagen museums are free and have late night openings. For individuals who are traveling on a tight budget, this is a great option.
If you are already in the harbour area to take a picture of the little mermaid statue then it wouldn't hurt to check out this street as well. The street is brimming with cafes and restaurants with traditional Danish fare despite its touristy nature. This street is a good area to people-watch.
6. Explore the paths around the lakes
The three lakes in downtown Copenhagen is a distinctive feature of the city. During the winter, some of the lakes develop such thick ice that ice-skating is permitted.
7. Watch the changing of the guard
A must see attraction; try to watch at Amalienborg, the royal residence. The guards officially change noon but the process begins at 11:30 am so the guards will be marching around town during that half hour.
8. Do as locals do-bike!
According to the official tourism site for Copenhagen, the majority of Copenhagen Hotels (90 percent!) offer bike rentals for a day at the price of 100 DKK. A 500 DKK down payment is required, which will be reimbursed upon return of the bike.
9. The Round Tower
If you like stars, visit the 350 year old Round Tower, which still continues to be a working observatory, The tower also offers panoramic views of Copenhagen proper.
10. Observe the architecture
Copenhagen is famous for its architecture both old and new . Some of the most famous and influential 20th and 21st century architecture was built here. Copenhagen hotels and national landmarks demonstrate the variety of architecture styles throughout the centuries.
