The Santiago Metro is fast, clean, and covers most of the city. Lines 1 through 7 connect the major neighbourhoods; Line 1 runs east–west through the centre from Cerrillos to Tobalaba and is the most useful for visitors. Trains run from about 6 a.m. to 11 p.m. (later on Fridays and Saturdays). You need a Bip! card (available from machines and kiosks at any station) to use both the metro and the city bus network (Red Movilidad). Load money onto the card and tap in and out. Single trips cost around 800 pesos in peak hours, cheaper off-peak.
Taxis are black with yellow roofs and are required by law to run the meter. Uber and Cabify both operate widely in Santiago and are often cheaper than taxis. Agree on a price or check the app before getting in if using a street cab.
The city is cyclable in the inner barrios, with a decent network of ciclovías (cycling lanes), particularly useful in Providencia, Ñuñoa, and Las Condes. Rental bikes are available through the Bikesantiago station network.
