While you are welcome to nurse or bottle feed your child or pump anywhere you feel comfortable within the Zoo, we also offer a private lactation space located inside Think Tank. This room is meant for single use only and includes two benches for seating, a small countertop, electrical outlets, and a locking door. This room does not have running water or diaper-changing facilities, but both can be found in nearby restrooms located behind the Conservation Pavilion next to Me and the Bee Playground.

To access the lactation space, download the free Mamava app.

Cleaning and Safety

The Smithsonian is implementing COVID-19 safety measures based on guidance from the CDC and local governments. See the Safety and Park Rules page for the latest guidance. If you feel sick, please do not visit the Zoo.

Bathrooms are open for you to wash your hands, and sanitizing stations can be found throughout the park. We also encourage guests to bring their own hand sanitizer for personal use. Bathrooms and high-touch areas around the Zoo are cleaned frequently each day.

Several restaurants and food trucks are open. Tables and benches are spaced according to social distancing best practices.

For the safety of guests, staff and animals, some areas of the Zoo may be closed during your visit. See the exhibits page for details.

As of March 11, 2022, masks are not required to visit Smithsonian museums or the Smithsonian's National Zoo.

While it will not be required, all visitors who feel more comfortable wearing a face mask during their visit are encouraged to do so.

The Smithsonian welcomes millions of visitors each year. We encourage visitors to maintain a safe social distance of six feet or more between households and groups when possible, but our museums get crowded, especially during peak visitation times. Visitors who wish to avoid crowds are encouraged to plan their visit during weekdays.

Animal care staff wear appropriate personal protective equipment (PPE) during their shifts to keep themselves and the animals safe, including any time they are working directly with animals, their food, or anything else an animal may come in contact with. We have also installed barriers throughout the Zoo to prevent visitors from coming within 6 feet of animals susceptible to the virus.

Food and Amenities

You may bring your own food and non-alcoholic drinks into the Zoo. Glass bottles are discouraged, as broken glass presents a danger to visitors, staff and animals. You may not bring in alcohol.

Food and drinks can also be purchased at restaurants and food trucks at the Zoo.

You can pay with cash or credit card at most vendors in the Zoo. For safety, we encourage you to pay with a credit card. Cash is not accepted for stroller and electronic convenience vehicle (ECV) rentals.
