Created by the National Park Service, this comprehensive app is your ultimate guide to discovering awe-inspiring national treasures, from Yosemite to Joshua Tree to the Statue of Liberty.

What we love: Accessing ranger-verified trail maps, self-guided tours, and on-the-ground accessibility information. Browse parks by activity (hiking, astronomy, climbing, scuba diving...you name it) or topic (African American heritage, immigration, night sky). No cellular signal where you’re headed? Download park details in advance for offline access.

Quick tip: Curious about the conditions in a particular park? Tap the Webcams button to view live feeds from over 100 locations across the nation.

Meet the creator: The app was created by National Park Service staff (people who really know their stuff!) to help you make the most of your adventure. Today the National Park System covers more than 85 million acres across the United States.
