Which directions work offline depends on the app.
Choose an app that fits your hike
Before downloading anything, check that the app has useful map detail for your destination and supports the kind of offline navigation you need. Compare trail or topographic information, offline walking or hiking directions, regional coverage, and whether downloads require a subscription. No single app is established as best for every location, so inspect your actual route in the app.

Test the saved map before the hike
While you still have service, open the saved map and inspect the trail at the zoom level you expect to need. Gaia GPS recommends switching the device to airplane mode to check downloaded maps before a trip. In that mode, verify that the map remains visible and that the app can show your location dot. This check confirms only what you tested; it does not guarantee every navigation feature works offline.

What works without cellular service—and what does not
GPS positioning and internet access are separate. Gaia GPS explains: “Your device does not need an internet connection (cellular or wifi) to provide GPS data to the app.” That statement is from the Gaia GPS Help Center article “Does Gaia GPS work offline?”, updated December 3, 2024.
GPS can give the app your location, but the app still needs map data stored locally to draw the terrain and trails. A map tile that was never downloaded may not load after service disappears. Directions and other features are app-specific: for example, Google Maps on Android does not offer offline walking directions, while Apple Maps documents offline walking directions in supported regions.

Check coverage and map boundaries
- Confirm the downloaded area contains the complete trail and likely junctions. Google Maps requires the whole route to fit inside the downloaded area for offline guidance.
- Inspect the actual map source and layer at the destination; Gaia GPS notes that coverage can be limited for some sources, and Apple and Google identify regional restrictions.
- Check that the map is legible at a useful zoom level, not merely that the download appears in a list.
- Do not assume that airplane mode preserves every app feature. Test the specific map and location display you expect to use.
Offline access is bounded by the area and detail you saved. Verify both before setting out, especially on remote or unfamiliar terrain.
