Start the season with a visit to a national park, and receive free weekend admission at all 417 sites during National Park Week.

Throughout the country, there will be free entrance to all National Park Service sites during the weekends of National Park Week on April 15, 16, 22, and 23. There are also free or reduced rate annual passes available for active duty military families, fourth grade students, senior citizens, volunteers and people with permanent disabilities.

“Our national parks are our national treasure,” said Secretary of the Interior Ryan Zinke. “My formative years were spent in Glacier National Park and one of my biggest mentors was a park ranger and football coach. The lessons you learn from the land and the park rangers cannot be learned anywhere else on earth.”

More information is available at National Park Week.
