You can view the web version at trails.colorado.gov. Or, you can search COTREX in the Google Play Store and Apple Stores for the mobile app.
Over three years in the making, COTREX apps utilizes data from 230 land managers making it the most comprehensive map of trails in Colorado.
COTREX is for everyone – hikers, bikers, ATV riders, equestrian riders, wheelchair users and others.
While we have built what we think is a robust tool that includes most features that land managers and the public want, there still may be locally desired features that may not be addressed in COTREX. For instance, the CBGTrails integrates with Strava and they are running a trailquest race to see which local can bike all trails in the Gunnison Valley Trail System the fastest (Spoiler: this lady won).
The trail near your house might not be on COTREX for a couple reasons:
The trail manager hasn’t participated in COTREX because of capacity issues or lack of GIS access.
Work with your land manager to find out if the trail is a legal route or if it isn’t on COTREX because of capacity issues. If the latter, please work with your land manager and have them contact Natural Atlas, the contractor who built COTREX (e-mail address forthcoming). If the trail is not a legal route, it will be entirely up to your land manager to decide if it should be inventoried or not. Be aware that inventorying a social trail generally involves environmental and planning reviews in addition to mapping its alignment. Your land manager may decide that it’s in the best interest of the property and the agency to not incorporate the trail into the system.
You may also submit map feedback directly by right clicking the map on the web or tapping the green plus button on mobile apps. Please provide as much detail as you can about what's missing or incorrect as well as contact information so we may request clarification if required.
Currently there are no winter trail uses on COTREX, but the state is looking into adding this feature. That said, you can visit the land manager’s webpage to see if they have their own winter maps or allow year-round use on their trails.
Yes! Users can complete “challenges” to earn badges. For instance, there is a Colorado State Wildflower Challenge where users must “note” (record in the app) one Colorado Blue Columbine in order to be awarded a badge.
Yes! Users can submit map feedback when trails or note trail obstacles such as downed trees.
Pending funding and other resources, the state would like to consider adding the ability to saved “measured” routes, including a “friends” feature, among others...
The contractors who built COTREX, Natural Atlas, will be refining the data until May 2019. At that time, the state may choose to renew their data maintenance contract. Land managers may provide specific feedback on the app or directly to Natural Atlas, submit full datasets when updated, or be set up with access and training to edit their data directly on trails.colorado.gov.
