The Continental Divide Trail "CDT"

Modern CDT GPX files have changed from using tracks to using waypoints. The reason is that waypoints display information such as intersections and water.

Two sites below have free GPX files of the CDT that can be downloaded, and then uploaded and displayed in CalTopo. Data can also be edited in CalTopo but it is easier to edit large GPX files on a computer, with software such as "Expert GPS." For example, in Expert GPS I was able to select only the CDT waypoints in Glacier National Park. Click the button below to see the result.

The CDTC is the major source of information on the CDT trail. There are several map sets available. One is a geospatial PDF set of maps where each half inch on the map represents a mile on the ground. They will print nicely and form the basis of paper maps that can be taken on the trail. Each topographical page shows an elevation chart, water sources, and other waypoint data.

For those that want gpx data, the CDTC provides a free file of 9060 waypoints. This file is too large for most gps units to handle. So to get smaller sections of the trail you will need to visit Bear Creek Survey Service LLC.

These guys are the original mapping crew. Their maps are the most up-to-date. However their web site is a little funky but good reading. They also publish books on each state section of trail. You have to buy the books but the gpx files are free. Start by clicking on the Trail Mapping tab along the top. Then click on "The Continental Divide Trail Mapping project." At the bottom of the page click on "Waypoints." Agree to their user agreement. Do a little reading. Finally you can find "Continental Divide Trail waypoints for the entire CDT - GPX - broken down by state-includes the alternates (the latest - for 2018 season)." Download and open the zip file.
