Initially set up in 2001 under the name Parque Biológico de Madrid, Faunia (as it is now called) aims at educating children (and adults) about the natural world by using state-of-the-art technology. A variety of ecosystems, from tropical rainforests to deserts and polar regions, have been ingeniously created within its 140,000-sq.-m (1.5-million-sq.-ft.) grounds. A wide variety of vegetation and hundreds of species of animals are on view. Facilities include dining areas, a nursery, an animal hospital, and a lake. Though it's out in the eastern suburbs of the city, it can be easily reached by metro or bus.
