On August 4th, all National Park Service entrance fees will be waived to celebrate the 4-year anniversary of the Great American Outdoors Act and this includes free entrance to Dinosaur National Monument. “The Great American Outdoors Act is one of the largest infusions of funding in the history of the National Park Service, enabling us to make long-needed repairs and improvements on everything from iconic buildings to trails, roads, bridges, lodges, campgrounds, utility systems and landscapes,” shares National Park Service Director Chuck Sams. Among the many uses of the funding, members of youth corps will complete approximately 435 historic preservation projects in parks throughout the country with Dinosaur National Monument being one of the locations. Celebrate this Sunday with free admission to Dinosaur National Monument or another national park service location.
