Smithsonian National Zoological Park

The Smithsonian National Zoological Park is one of the most celebrated free zoos in the world, located in Washington, D.C., and welcoming more than two million visitors each year. Home to a breathtaking range of wildlife — including giant pandas, Asian elephants, lions, black-footed ferrets, naked mole-rats, and sloth bears — the zoo operates as both a world-class public attraction and a leading center for wildlife conservation science. Live animal cameras allow guests to connect with animals around the clock, while on-site educators offer interactive experiences and programming for all ages. Beyond the exhibits, Smithsonian scientists conduct vital research at a satellite campus in Front Royal, Virginia, working on cryopreservation, endangered species recovery, and field ecology projects. The zoo's combination of free access, iconic animals, and rigorous conservation mission makes it a truly unparalleled institution for wildlife education and preservation.
