Kids love this cable car, which takes you from the Rosaleda gardens in the Parque del Oeste to the center of Casa de Campo in about 10 minutes—note though, that this is not the best way to get to the zoo if you're with children because the walk from where the cable car drops you off to the zoo and theme park is at least 2 km (1 mi), and you'll probably have to ask for directions. You're better off just taking the bus to the zoo and saving yourself the walk, or ride the Teleferico out, and back, then bus it to the zoo.
