Frequently Asked Questions

Q: How do I create Track Recordings?

You may record tracks as follows:

  • The CBGTrails app (this is the easiest way)
  • Strava
  • Fitbit
  • Garmin or GPS units like it
  • Manual .gpx track upload

If you use a track recorder that can sync to a Strava Account (e.g., via the Garmin Connect app), you can use Strava to automatically sync your tracks to TrailQuest.

Q: How do I download maps?

Most of the CBGtrails area does not have cell service. Therefore, you must download maps so they will be accessible offline before you head out on the trails.

To download maps go to the "Map" screen and then click the download button in the right-side toolbar. From the map download screen you can download preconfigured map areas by simply pressing the download icon (i.e., inside the blue squares depicted below). For all other areas, you'll need to download a custom map. In iOS, the custom map download tool is comprised of a red download area box and grey handles you can drag. Once you set the custom area, click the download icon in the middle of the red square and give it a package name. Make sure the map downloads completely before you leave service.

The Android user interface is not quite as slick (Mapbox's Android SDK is behind iOS), but it works essentially the same way. The map bounding box is selected by clicking the top right-hand and bottom left-hand corners of the desired map area to download.

Note: the downloadable trail map works for all areas of Colorado.

Q: What are trail observations, and how do I submit them?

Trail observations are included in the app and website interactive map to crowdsource trail information.

  1. Trailheads - No maps include all the formal trailheads in the Gunnison country. Therefore, we’d like your help geolocating all formal trailheads in the area. We attach Google map directions to trailhead observations so everyone can get turn-by-turn directions to formal trailheads.
  2. Trail Signs - We use heatmaps of anonymized user tracks + trail signs to map trails according to where users traveled and how the trails are signed on the ground. Therefore, crowdsourcing of trail signs is the most effective way to make sure trails are accurately mapped.
  3. Trail Reports - Use this observation type to create observations of anything that is not a trailhead or trail sign. For example, you can post observations of trail-related issues that need attention (e.g., down trails, trail repairs needed, etc.) Land Stewards use these reports to identify trail to-do tasks. Furthermore, you can post reports of topics you think other users may find interesting. Note, inappropriate reports may be flagged and/or deleted.

If your observation does not fit into any of these categories, enter a custom tag in the tag box.

You can create trail reports from the CBGTrails interactive map by clicking the report button as shown below.


Then, you’ll click submit report, enter your information, and add pictures if you like.

And, of course, you can create reports from the CBGTrails mobile app as well by clicking a similar button in the bottom navigation bar. Reports that you create offline, without a cell signal will upload when you return to internet land.

Trail Observation Examples

Trail Reports

The snow melted out super late in 2019, and everybody was wondering which trails were opening when.

For trailhead observations, it is helpful to take pictures of trailhead maps and to note the amenities available.

Trail Sign

For trail sign observations, it is extremely helpful to take pictures that inlcude both the sign and carsonite signs designating the activities that are permitted on the trail. The official designations are used to tag OpenStreetMap data, which we then use to create the multi-user trail map style.

Your trail sign observations help to crowdsource open trail data!

We combine anonymized and unpublished user track data + your trail sign observations to map trails in OpenStreetMaps, one of the coolest open data projects ever created. In short, your trail sign contributions serve to create an open free trail map that all apps can use, including CBGTrails. We build the map this way because we believe information about public trails should be free and open to the public.


The best way to make sure our trails are accurately mapped is to submit tracks to CBGTrails and contribute trail observations of trail signs.
