Our national park era is in full swing—and the 331 million visitors to more than 400 parks, memorials, and historic sites across the nation last year might agree too. Whether you’re planning a weeklong excursion or a day trip to a national park near you, these apps can guide you on every step of your adventure.

Plan your excursion
Make the most of a trip to Old Faithful, Half Dome, and other top destinations with the National Park Service app. Get self-guided tours (some audio based) for select locations as well as the best spots to watch a sunrise, a calendar of park events and seasonal closures, and more.
To gear up for your trip and take outdoors-skills classes for beginners and enthusiasts alike, check out the REI app.

Pick a path
Check out the national park guides in AllTrails—or search by city, park, or trail name. The app’s powerful filters can help you find a hike that suits the length and difficulty you’re looking for. Traveling with dogs or children, or need wheelchair-accessible routes? You’ll find filters for those too.
Strava helps you discover hikes and trails others are exploring. View the Segments near the parks you want to visit, or join communities like Black Trail Runners to find your next adventure.

Elevate your experience
PeakVisor uses AR and your iPhone’s camera to display the names and elevation of nearby mountains.
Birda encourages you to marvel at the hawks, eagles, and white-breasted nuthatches around you. You can keep track of what you’ve spotted and see what species other users have found.
Planning a sunrise trek or want to photograph a peak just as golden hour hits? Fire up the comprehensive sun-tracking app Lumy.

Savor a moment of mindfulness
NatureDose helps you tally how much time you’ve spent in nature—and reminds you how important this is to your overall well-being.
If you can’t make it outdoors, listen to Headspace’s National Park sleepcasts to find a moment of calm inspired by the sounds of Joshua Tree, the Grand Canyon, and other parks.

Go beyond the trail
Treecard plants a tree for every 10,000 steps you take—and when you make climate-friendly purchases in its marketplace.
