Most tourist sites are within the city centre, which is easy to navigate on foot. However, Athens has an extensive public transport network consisting of buses, trolley buses, trams and a fast, three-line underground metro service. The metro and the tram network are especially useful for tourists.
Transport is cheap, but often overcrowded, especially during rush hour (1-3pm). Most public transport operates until midnight, with a limited night bus and tram service operating along major routes.
Although taxis are plentiful, it may be difficult to get one during rush hour. For this reason, it's not unusual to share the ride with other passengers. Taxis are inexpensive, but visitors should always check that the meter is on and set to the minimum fare. Drivers often attempt to overcharge tourists. Legitimate surcharges can increase the final bill, but these should be displayed on the dashboard.
