Getting around Washington DC is relatively easy as most attractions are within walking distance of one another and the streets are fairly easy to navigate. The city is laid out in a circle around the White House, with 'spokes' radiating out from it. Washington DC has an excellent public transport system that includes buses and the Metrorail subway, which has stations at or near almost every tourist attraction. The system operates until midnight. The efficient Metrorail subway system provides services throughout the city, and to the Virginia and Maryland suburbs, and is used by means of a computerised fare card. The extensive Metrobus network fills in the gaps, but is more complex to use and is slower due to heavy traffic; bus transfers are free and valid for two hours from boarding. Bus, train, or combined one-day passes are available. Although most visitors to Washington DC arrive by car, it is often easier to use public transport as traffic is heavy, and parking in the city is difficult and expensive. Taxis are a good way of getting around for short distances and they are cheaper than most other major cities in the US.
