National Zoo
At the Smithsonian National Zoological Park you'll find lions, tigers, giraffes and the zoo’s beloved giant pandas among the 1,500-plus animals that call the 163-acre park home. The zoo’s habitats feature animals from 300 different species and about 25 percent of the zoo’s residents are endangered. All of the animals at the National Zoo – which is also a global research center and conservation center – are cared for by world-class zoologists and veterinarians. Like all Smithsonian museums, admission is free of charge.
