Start the day by touring Amalienborg Palace, which is the winter residence of the Danish royals. Watch the changing of the guards and witness the impressive rococo-style interiors of the palace.
A must-see attraction in Copenhagen is the Tivoli Gardens, a popular amusement park that boasts amazing architecture, various rides, and delicious food options.
One of the most popular tourist attractions is the Little Mermaid statue. It was inspired by the fairytale story of the Little Mermaid and has attracted visitors for over hundred years.
Many of these attractions are walkable or easily accessible by public transportation. You can purchase a City Pass which includes unlimited access to buses, trains, and Metro transportation for DKK 80 (~$12 USD) per day.
If you have more time, you can visit the National Museum of Denmark or the Christiansborg Palace. If you have less time, you can eliminate the Amalienborg Palace and spend more time at Tivoli Gardens.
Copenhagen international airport (CPH) is located 8km south of the city center. It is the largest airport in Scandinavia and serves over 30 million passengers annually.
