Copenhagen's public transport is exceptionally safe, reliable, clean and inexpensive. The Metro, buses and trains in the city and surrounds operate on a one-fare system, where tickets are valid for all three types of transport with no extra cost for transfer.Bus services are frequent between 5am and 1am, with night buses operating after regular hours. The Metro runs from Vanlose Station to Lergravsparken in East Amager, to Orestad in West Amager and to Frederiksberg, operating on a 24/7 basis.A favourite mode of transport for locals and visitors is the bicycle, and Copenhagen has cycle paths and routes along all major streets. Copenhagen is well supplied with licensed taxis. Traffic is usually congested in the city centre and a car can be a liability rather than an asset.
