When you’re out camping, you might not have access to a data connection, so it makes sense to download content beforehand. If you use Apple Music or Spotify, you can download playlists to your Apple Watch for offline listening.
This way you can stream music on Apple Watch without your iPhone by connecting it to Bluetooth headphones. The Apple Watch Series 5 and later come with 32GB of storage, while the Watch Series 9 and Watch Ultra 2 have 64GB, which is more than enough for several hours of music playback.
You might also want to download maps on your Apple Watch. Apple Maps lets you download a specific area to your iPhone, and then view it on your Apple Watch. You can then get turn-by-turn directions on your Apple Watch, provided your iPhone is on and within Bluetooth range. Alternatively, use an app like WorkOutDoors can work. While it’s primarily an outdoor workout app for Apple Watch, it also has maps that can be downloaded for offline use and viewed without starting a workout.
With WorkOutDoors on Apple Watch, you can access topographic vector maps with contours and hill shading, and pan and zoom maps. If you’re using the app while hiking, you’ll be able to view waypoints and a breadcrumb trail of your route.
