Visitor Center
There is no visitor center on the parkway itself. Information, brochures, maps, and National Park Passport stamps are available at parkway headquarters and at visitor centers at Arlington House, Glen Echo Park, and Great Falls Park.


You may bring your pet with you to the park. With the exception of service animals, pets are not permitted in historic homes, in visitor centers, or on ranger-led programs.

At all times, pets must be restrained on a leash no more than six feet long. Leashes protect pets from becoming lost and from other hazards, such as sick, injured, or rabid animals. Leashes also help protect park resources, including wildlife and vegetation.

Pet owners are responsible for disposing of pet waste in a trash can.

Pets should not be left unattended. Summer sunshine poses a threat to pets left in vehicles. On a bright, sunny day, even in temperatures as low as 60° F, temperatures inside a vehicle can reach dangerous levels. On an 85-degree day, the temperature inside a car—even with the windows cracked—can reach over 100 degrees within 10 minutes.
