Getting from the airport to the city centre
The easiest way is to use the Metro, located in Terminal 3 - past the entrance to the trains. You can get a (3-zoner) ticket for 36 DKK from a vending machine or at the DSB counter. Remember to stamp it at a yellow machine on the platform.
Getting to the Niels Bohr Institute
Blegdamsvej 17 is marked on this map. Detailed directions on how to reach the institute (as well as other useful information) can be found here. For metro, bus and S-tog (light train) journeys, www.rejseplanen.dk can be used to find routes. If coming by Metro you can get off at Forum St., then walk to the stop (Rosenørns Allé) around the corner to take bus 3A towards Nordhavn St. which stops in front of the Institute (Irmingersgade). You may use the same ticket - show it to the Driver as you get on.
