For four days this month—April 15, 16, 22 and 23—the National Park Service along with the National Park Foundation is offering free entrance into all national park sites in the U.S.
Be aware, camping and other fees still apply, but you can see everything for free. This includes Crater Lake National park and Lewis and Clark National Historic Park.
