This year marks the 100th anniversary of the National Park Service. Established on August 25, 1916, by President Woodrow Wilson, the agency is responsible for managing the 59 national parks across the country, as well as historical landmarks and monuments, like the Statue of Liberty.

With celebratory events planned throughout the year, it’s a good time to check out these national treasures. If you’ve never ventured outdoors before, don’t fret: Use your smartphone as a personal guide. There are various apps to help you find your way around a national park, and the Find Your Park website is a good resource for getting started. Here are the apps we’ll be using, along with extra gear to capture the moment and ensuring we find our way back to the visitors’ center.
