Can you put in gps coordinates into Google maps? I ask cause like you we do some hiking and the only way to find some trails is by gps coordinates
Yes, you can use lat/long coordinates with Google Maps, but I've found that for hiking I prefer apps that specifically map trails and work offline. There are a bunch of free ones in the Google Play store. You just have to remember to download them at home and then start them up so they'll grab the topo maps that you need for wherever you're going.
When we were in Joshua Tree NP in the spring we were on a trail that followed several sandy washes and the cairns to mark the trail were rather sparse, so it was really nice to be able to fire up an app and know where the actual trail was and see our little blue dot from the GPS.
