Each year millions of people visit Grand Canyon, one of the Seven Natural Wonders of the World. At Grand Canyon Association (GCA), we seek to enrich the visitor experience through knowledge. Your support of GCA helps make this possible.

It is GCA’s mission to support educational, interpretive, and visitor service programs at Grand Canyon National Park. As a nonprofit membership organization, we publish, sell, and give away a wide variety of publications and related materials to enhance visitors’ understanding and appreciation of Grand Canyon.

We also operate bookstores throughout the park, support scientific and cultural research through the park’s Science Center, and fund acquisitions for the park’s research library. Through our Grand Canyon Field Institute, GCA conducts hands-on, experiential trips into the park.

Since 1932 we have provided Grand Canyon National Park with over $20 million in financial support. We believe that by educating visitors about the value of this beautiful place, they will return home with a better understanding of, and a renewed commitment for, all public lands.
