The maps are available for download as state or section bundles in three file types, serving hikers with a variety of navigation needs and trip lengths — from day hikes to thru-hikes.

While we work hard to provide the most comprehensive and up-to-date information in these maps, users are solely responsible for their own safety and planning while on the CDT. CDTC, the U.S. Forest Service, and any other parties are not responsible for errors, omissions, or inaccuracies in the maps or data. All information is subject to change. Please refer to multiple sources, including local land managers and the CDTC Closures & Alerts page, when preparing to travel on the CDT.
The CDT Map Set is a free public resource made possible by generous donations and support from the CDT community. If you find these maps useful, please consider making a donation to support their continued maintenance and production.

Bear Creek Survey Maps – Developed by the former CDT organization and Jerry Brown of Bear Creek Survey, these map guides reflect the most current line data for the CDNST available. These guides will give you the most accurate way point data for the “official” CDNST route, including water sources, critical intersections and general know where you are or need to be information. The data contained in the CDT app is the same as what you will find on the Bear Creek Survey Maps, we highly recommend you combine these with Yogi’s CDT Handbook and Planning guides for the best adventure possible on the CDNST!
