This weekend is the perfect opportunity to pitch a tent, take a hike, or tour a national park near you to celebrate National Park Week, from April 17 to April 25. The park service is also waiving the entrance fees at all 392 parks in the U.S., and many parks are holding special events during the week, including some Earth Day activities.

Learn more about National Park Week on the National Park Service website.
