At the PCTA offices, we use Google Earth heavily. Short of being in the backcountry, it’s often the best way to experience a section of the trail. Visit the link for tips on how to load the PCT in Google Earth.
The U.S. Forest Service stewards a digital centerline for the PCT. The files below are hosted on the US Forest Service PCT webpage.
Halfmile’s PCT data is also available for Google Earth and GPS.
