National parks guide and maps

“Climb the mountains and get their good tidings. Nature’s peace will flow into you as sunshine into trees.”

So wrote John Muir, who, according to many historians, convinced President Theodore Roosevelt to expand the National Park System during a three-day camping trip the two men took together in Yosemite.

Today the National Parks System spans 84 million acres and welcomes more than 300 million recreational visitors each year. REI Co-op National Parks Guide is among the most comprehensive guides to these treasures.

A few of the National Parks detailed in the app, sorted by popularity.

Covering 50 popular sites—from Acadia National Park, in Maine, to Zion, in Utah—this photo-rich app leads you through every step of your journey, from planning a trip to finding the most scenic trail to locating the hot springs once you’ve arrived.

Visit the “Gems” section of each guide for the park’s top spots.

For each site, you’ll find general tips (did you know the Grand Canyon’s North Rim Campground stays open two weeks longer than the Grand Canyon Lodge?), details on camping and lodging, and average temperatures and precipitation through the year.

Zoom in on the topographical maps for specifics on a park’s trails.

The app’s trail guides truly shine. In addition to topographical maps, there are thoughtful write-ups about points of interest and the paths to them. You’ll get an honest assessment of a hike's difficulty, as well as helpful hints (like where to find shade along the way) from those who've walked the path.

“Between every two pine trees there is a door leading to a new way of life,” John Muir wrote. This app can help you take a step in that direction.
