A number of GPS files of trails can be downloaded for use on your mobile device. Currently they are in .kmz format – useful with Google Earth, Guru Maps Pro, RidewithGPS and some other applications.

For a complete set of gps files for all of the trails shown on the maps on this website, download this kmz file:
