Trail data

I was wondering if the trail location data that Caltopo is using is available for free somewhere. I’m just looking for an gpx or kmz file so that I can overlay trails on a geologic map. Thanks!

    The MapBuilder layers are based on OpenStreetMap; there's a bit of a learning curve but you can download data from them using tools such as overpass. The underlying data for the FSTopo maps is available from the Forest Service. I'm not aware of a source for the road/trail data behind the USGS 7.5' topo maps.
