The easiest way to get around Cuzco is on foot, as many of the hotels and tourist attractions are close together. That said, travellers should remember that Cuzco is a high-altitude destination, which makes walking tiring. Visitors should hire the city's relatively inexpensive taxis for longer distances. Taxis are regulated and fares are standardised, though the vehicles are not metred. For this reason, tourists should call a registered taxi company if they're travelling at night, to the airport, or to the bus or train station.
