When Gaia GPS users publish tracks, you can add them to your own account.
To find awesome trips that have been shared publicly:
Select any of the user trips you see on the gallery, and search the gallery for places you'd like to go, too.
Or, from the main map on gaiagps.com, make sure you have Public Trips toggled on and search for your destination.
Once you've found a user-added track you'd like to save, click on it to reveal the name.
Clicking on the name will take you directly to the track details page.
Finally, select "Add to My Tracks" from below the Title of the track to add it to your account.
Please note: user photos will not be saved to your account, but the waypoint data from those photos will.
