Download the map before you lose service, then check that the trail is visible while your phone is offline. Your phone’s GPS can still show your location without cellular data or Wi-Fi, but the app needs map data saved on the device to draw the area around you. Offline directions and trail detail vary by app and region.
Choose an app that fits the hike
Before downloading anything, check whether the app provides the kind of offline information you need: basic map coverage, walking directions, or hiking-oriented trail and topographic maps. Also check whether downloads require a subscription and whether the relevant map source covers your destination. No single option is established as best for every trail.
| App | Offline capability established by its documentation | Important limit |
|---|---|---|
| Google Maps on Android | Download a map area and navigate offline by driving. | Offline walking, bicycling, and transit directions are unavailable. For driving, traffic information and alternate routes are unavailable. The entire route must fit within the downloaded area. Google Maps Help |
| Apple Maps on iPhone | Offline maps can provide walking directions where available. | Offline maps are not available in every country or region. The documentation of walking directions does not establish topographic or trail-specific coverage. Apple Support |
| Gaia GPS | A hiking-oriented app with downloadable maps and offline routing data. | Offline downloads require a subscription. Coverage depends on the selected map source; Gaia GPS recommends High resolution for hiking. Gaia GPS Help Center |
Check the intended trail in the app itself: a general map’s offline directions do not necessarily include the trail detail you want, and a hiking app’s available layers can vary by location.
Download the map before leaving service
Use Wi-Fi or cellular data while you prepare. Search for the hike or pan to it, select a region that covers the full route, and start the download. Include nearby junctions, access roads, and a reasonable margin in case you need to adjust your route. Check the app’s offline-map list or download status to confirm that the area was saved.

Check the map while the phone is offline
Before departure, open the saved map and zoom in far enough to inspect the trail and its junctions. Then turn on airplane mode and check that the map remains visible and the app can show your location dot. Gaia GPS specifically recommends this kind of offline check. Do not assume that passing it means every feature in the app will work without a connection.
- Confirm the downloaded area covers the entire planned route, not just the trailhead.
- Inspect the map at the level of detail you expect to use on the hike.
- Check that the map source has coverage for the destination; some sources or regions have limited coverage.
Gaia GPS says that downloaded maps are saved directly to the device for offline access. Its help center also explains: “Your device does not need an internet connection (cellular or wifi) to provide GPS data to the app.” Gaia GPS Help Center, updated December 3, 2024

What still works without cell service?
A GPS-capable phone can determine its location without cellular data or Wi-Fi. Internet access and GPS positioning are separate: GPS can provide the location dot, while the app needs map content stored locally to show the surrounding map. A map area that was never downloaded may not load after service disappears.
Offline navigation is a separate capability from offline positioning. Apple Maps documents offline walking directions on iPhone where available; Google Maps on Android does not provide offline walking directions. Gaia GPS says its download flow includes offline routing data. These differences are why the airplane-mode check should cover the functions you actually expect to use.

Know the limits of an offline map
- Coverage is regional. Apple and Google identify places where offline maps are unavailable, and Gaia GPS notes that map sources can have limited coverage.
- Downloads cover only the selected area. Google requires an entire route to fall inside the downloaded area for offline guidance.
- Map layers and detail vary. A downloaded map is not a guarantee that every source, layer, or feature is available for every trail.
- Offline does not mean fully connected. Features that need live information—such as Google Maps traffic—will not be available offline.
Verify the specific route and map detail in the app before you leave, especially for remote or unfamiliar terrain. Gaia GPS coverage and download guidance; Google Maps offline limits; Apple Maps availability
