The Zoo is open! Entry passes are required for all guests, including infants. All visitors ages 2 and older are required to wear a mask in all indoor spaces at the Zoo, regardless of their vaccination status. Fully vaccinated visitors do not need to wear a mask in outdoor areas. Small Mammal House and Reptile Discovery Center will be closed Sept. 18 due to HVAC issues. We apologize in advance for any inconvenience.
Smithsonian scientists are collaborating with the American Prairie Reserve in Montana to help understand, restore and preserve this wild landscape. Follow ecologists into the field as they attempt to answer big conservation questions in an even bigger place.
