Because Copenhagen International Airport has to host up to 20,000 people per day in transit alone, the airport features state of the art facilities, including restaurants, shops, work areas and lounges. If you have a couple of hours to spare, you can take a guided city tour which can be booked at the airport.
Copenhagen International Airport has four terminals, with the rail station located under terminal 3. From here, trains and metro rails can take you to Copenhagen's central station in 14 minutes. The trains depart to Copenhagen from platform 2 every 20 minutes. Shuttle busses are also available to take you to the different terminals.
Copenhagen is a huge city containing several districts and is a metropolis for shopping and nightlife, so it is very easy to lose track of time. Maps are available at the airport from tourist information, but the main districts are Indre – the heart of Copenhagen, Christianshavn, Nørrebro, Amager – the airport district, and Vestegen.
The Central Station of Copenhagen (called Københavns Hovedbanegård by the locals) is the largest station in Denmark and the hub for all train traffic in the country. There are two metro lines in Copenhagen, with the city center as its base, giving you access to an affordable and fast way to travel in and around the city 24 hours a day. The trains depart every 4 minutes. The M2 is the train you want to take to and from the airport. When arriving back at the airport, you will get off at platform 1. It also takes you through the inner city and the Christianshavns Canals, passing a few tourist attractions along the way. The third metro line in Copenhagen will be completed in 2018.
Airport shuttles to the city and regular taxi services are abundant at Copenhagen Airport. All registered taxis can be identified by a registration number and the “Taxa” sign on the roof. Available taxis will display the word free (fri) and most drivers can speak both English and German. Do keep a look out for pirate taxis, and do try to avoid making use of them. They lack legal and safety protection. As opposed to most taxi services in other countries, all prices are inclusive of VAT and tips.
At Copenhagen Airport, buses can be found between terminals 2 and 3. They depart every 10 to 20 minutes, running from 5.30 am until midnight. Buses are very easy to find, considering that there are over 400 lines. In the city the two main terminals can be found at the Town Hall Square and at the Central Station. Always do try to get your hands on the latest route maps at the relevant stations, since the routes can change frequently.
If the option of renting a car at CPH appeals to you, do keep in mind that everyone drives on the right hand side of the road, with their headlights on. Always. The speed limit is 50 km/h in towns and 110km/h on highways. Car rental offices can be found at both terminal 1 and 3 at Copenhagen Airport. You can choose between Avis, Hertz, Europcar, Budget and Sixt.
If you have some time to spend in Copenhagen, a trip on the harbor buses is a must. You get to explore the city from the waterfront and seaside. Those buses make several trips daily in the harbor, visiting the port, Opera House and the Royal Library.
