Yellowstone National Park is funded through a combination of federal appropriations, recreation fees, and private philanthropy. The largest portion of its budget comes from the National Park Service (NPS) annual budget, which is passed by Congress. For 2026, the budget request focuses on "Resource Stewardship" and "Visitor Services" to manage record-breaking crowds. A significant secondary source is the Federal Lands Recreation Enhancement Act (FLREA), which allows Yellowstone to keep approximately 80% of the entrance fees collected at its gates (currently $35 per vehicle) to fund local projects like road repairs and trail maintenance. Additionally, the Great American Outdoors Act provides dedicated funding to address the park's "deferred maintenance" backlog. Finally, non-profit partners like Yellowstone Forever raise millions in private donations for specific research projects, such as wolf restoration or grizzly bear tracking, which might not be covered by standard government funds.
