An adventure not to be missed while visiting Santiago is a funicular ride in Parque Metropolitano. The entrance (called the Pio Nono station) in the Bellavista neighborhood is shaped like a medieval castle. The rail cars clatter up over 1,600 feet of track with a quick stop at the zoo before reaching the second station at the summit of Cerro San Cristóbal. The funicular was built in 1925 and became a National Monument in 2000.
