    The free NPS app lets you download park maps for offline use, find ranger programs, track passport stamps, and access audio tours — no cell signal needed.

    1

    Download the NPS app

    ~22s
    Search for "NPS" or "National Park Service" in the App Store (iPhone) or Google Play Store (Android). The official app is published by the US Department of the Interior and has a green icon with the arrowhead NPS logo. Download and open it — no account or login is required to use the basic features, though creating an account lets you track your passport stamps across devices.
    2

    Download a park for offline use

    ~37s
    Use the search bar to find the park you plan to visit — for example, "Grand Teton" or "Acadia." On the park's main page, look for a "Download" button (it may appear as a cloud icon with a downward arrow). Tap it to download the park's complete information package, including maps, trail data, and program listings. The download size is typically 50 to 200 megabytes, so do this while connected to Wi-Fi at home before your trip to avoid using your phone's cellular data.

    Quick Tip

    Quick Tip: Download your park at least the night before you visit — do not rely on finding Wi-Fi at a park visitor center, as those networks can be slow and crowded.

    Find ranger-led programs

    ~24s
    Inside a park's section of the app, tap "Things to Do" or "Programs and Events." You will see a list of ranger-led programs with dates, times, meeting locations, and descriptions. Programs range from short 20-minute talks at a scenic overlook to 2-hour guided hikes. Many programs are designed for all fitness levels and are explicitly family-friendly. These are free to attend — no reservation needed in most cases, though some require sign-up at the visitor center.

    Collect virtual passport stamps

    ~27s
    When you arrive at a park, tap the stamp icon within that park's section of the app. The app uses your phone's GPS to confirm you are actually at the park location before issuing the stamp. Each stamp is saved in a digital "Passport Book" inside the app — you can see all the parks you have visited in one scrollable collection. If you also have a physical passport book, many visitor centers still offer free ink stamps at the front desk.
    5

    Use audio tours while exploring

    ~38s
    Some parks offer audio tours accessible through the NPS app — narrated recordings that play as you drive or walk through specific routes, similar to a museum audio guide. Look for "Tours" within a park's section of the app. These tours work offline if you have downloaded the park content in advance. Audio quality and length vary by park — some parks have detailed multi-stop driving tours while others offer shorter trail-focused narrations.

    Quick Tip

    Quick Tip: Check the "Accessibility" section within each park's app page for details about wheelchair-accessible trails, paved paths, accessible restrooms, and services for visitors who are deaf or hard of hearing — this information is often easier to find in the app than on printed maps.

    The National Park Service (NPS) app is the official free app from the US government for visiting national parks. It is available for both iPhone and Android phones and is packed with information that genuinely helps during a park visit — not just park brochure text, but detailed trail maps, ranger program schedules, wildlife information, and accessibility details.

    One of the most valuable features is the ability to download an entire park's information for offline use before your trip. Cell service in many national parks is limited or nonexistent — once you are deep in Yellowstone or hiking in a canyon, your phone may show no bars at all. If you downloaded the park before leaving your hotel or home, the app still works completely — maps, trail information, points of interest, and more are all accessible without an internet connection.

    The NPS app also includes a digital passport stamp feature. The National Parks Passport program has been popular for decades — visitors collect rubber ink stamps from each park they visit in a small passport booklet. The app adds a virtual version: each time you visit a park and check in through the app, you earn a digital stamp. This is a fun way to track which parks you have visited over the years.

    The app is also a good resource for planning. Before you go, browse ranger-led programs (free walks and talks led by NPS rangers), read about the park's history, check current road closures, and look at photos from other visitors. Ranger programs are one of the most rewarding parts of a national park visit and are completely free — the app makes it easy to find and plan around them.
