Metrocables

There are two cable car extensions of the Metro: For the line K take a metro train to Acevedo station and from there take the Metrocable up to Santo Domingo for a nice view over the city. The cablecar is included in your metroticket. Go during the day and walk around to see what working-class people live like. The area at the top sees tourists so there are little stands set up and people selling empanadas and other things. You can stop at a little bar and have a beer. Don't stray too far or off the beaten path in this neighborhood, though. For those so inclined, there are young people that give tours waiting at the top wearing t-shirts that said "guia" (guide).
From Santo Domingo you can take the line L to have an even better view over the city and ride some time over a forest to the Parque Arví. Taking this touristic line costs COP$11,150 (December 2022). The last departure from Parque Arví is 18:00.
Also recommended is taking the metrocable located at San Javier up to La Aurora (J line). Although there is nothing special to see or do at the top of the cable car route, the trip itself is longer and more interesting than the cable car that goes to Santo Domingo.
