Friends Groups

Over 200 friends groups partner with national parks nationwide, carrying out projects and programs that are as diverse as the parks they partner with. Despite this diversity, they all have one thing in common -- their passion for parks.

From raising funds to rehabilitate centuries-old structures and maintain visitor facilities, to enhancing educational opportunities, hosting special programs and events, and supporting critical research and restoration projects, friends groups benefit parks in so many ways.

There are many ways you can participate in the activities, initiatives, and events of park friends groups. Select your favorite park and discover how you can get involved in partner efforts!

Cooperating Associations

In many national parks, not-for-profit organizations known as cooperating associations enhance visitor understanding, knowledge, and appreciation of national parks through the services they provide, such as operating bookstores, developing park related publications, merchandise and audiovisual programs, and supporting educational and interpretive programming.
