Mission

Grand Teton National Park Foundation (the Foundation) is a private, nonprofit organization whose mission is to partner with Grand Teton National Park to steward, protect, and enhance all that is special in the park. Budget limitations, combined with increasing visitation, led the National Park Service to create partnerships with organizations like the Foundation to raise private money for special park needs. The Foundation initiates improvements, critical research, and projects that improve visitors experiences, creating a solid future for Grand Teton. Since 1997, the organization has raised funds for efforts that connect youth to nature, preserve cultural resources, protect wildlife and natural resources, and enhance visitor experiences. In addition, the Foundation has completed capital projects such as construction of the Craig Thomas Discovery and Visitor Center, the conservation of 1,280 acres of critical wildlife habitat that was formerly owned by the state of Wyoming, the renewal

State Lands/Kelly Parcel:In 2025, the Foundation supported the park in its decades-long effort to purchase the 640-acre Kelly parcel from the state of Wyoming. The Kelly parcel was the largest tract of unprotected land remaining within the boundaries of Grand Teton National Park. The elevated square-mile provides sweeping views of the Teton Range and includes critical habitat for numerous species of wildlife. The parcel is also located within a key migration corridor for pronghorn, elk, and mule deer. If the Kelly parcel was not permanently conserved as part of Grand Teton National Park, this inholding could have been developed, risking the loss of vital habitat in the Greater Yellowstone Ecosystemone of the last remaining, nearly intact temperate ecosystems on the planet. The permanent conservation of the Kelly parcel was a major conservation achievement for Grand Teton National Park and the Foundation in 2025.

WINTER AND SUMMER TRAILS:The Foundation funds grooming three times per week of the 14-mile stretch of road between Taggart Lake Trailhead and Signal Mountain on the Teton Park Road. Regular grooming allows visitors to easily explore on Nordic skis, snowshoes, or foot to experience this special season in Grand Teton National Park. In the summer months, the Foundation is funding a multi-year effort to renew key destinations along the Teton Crest Traila 45-mile route through the parks high country that was originally constructed by the Civilian Conservation Corps in the 1930s. Summer 2025 marked the sixth year of project work on the Crest Trail. Improvements were completed near Marion Lake and Fox Creek Pass, making it more safe for hikers to this remote alpine area.
