■ ABOUT COTREX
Colorado Trail Explorer aims to map every official trail in the state of Colorado. COTREX connects people, trails, and technology by coordinating the efforts of federal, state, county, and local agencies to create a comprehensive repository of recreational trails for public use.
COTREX is unique in that the app only shows information from official sources. No unreliable crowdsourced information or recommendations from someone on the other side of the country. Everything you see in COTREX has been reviewed and approved by the managers and experts local to that area.
This project is led by Colorado Parks and Wildlife (CPW) and Department of Natural Resources, but is only made possible through partnerships with organizations at every level statewide. COTREX represents a seamless network of trails managed by over 230 land managers.
■ DISCLAIMERS

+ Easy to track routes or make your own after the fact or as planing Downloadable maps is awesome Great info on all the trails I know of Elevation gain and loss (when it works) Free - Had to reinstall because it couldn't find my location Doesn't say trail difficulty. Would be a major plus for mountain biking Elevation gain/loss is buggy. By definition if I travel on a loop they should be equal but one is often several hundred feet off from the other Sometimes can't figure out that trails connect
★★★★★Richard Shelquist· Dec 3, 2020
Wonderful app with amazing features!.. And it's free! Handy measuring tool snaps to available trails. Downloadable maps for exploring in the mountains when you have no internet connection. I find this app more useful than All Trails for hiking in Colorado. I just wonder why so few people have reviewed this great product. Perhaps they're all out hiking.

3 years after release this CPW partner app still doesn't have a hunting/fishing layer? No STLs, no SWAs, and no WIA layers. Might be nice to support the folks who pay for all the outdoor fun.

Tap on a trail, and you get some info, but I'm looking for the rating of the trail and whether there's a fee. Why does it have to zoom way out when I search? I find an area I want to explore and search for trails classified as easy, and it zooms out so that I don't know where I was. (Just like Google Maps. Just as annoying.)

Colorado trail-not great. Old app from a few years ago was far better. Showed the actual CT and people were able to submit important things like water locations and suggested camp sites they find along the trail. Won't be using this app. Also, I brought up superficially the CT on the map and when I zoom in to you know, see the trail, there are tons of other trails that show up highlighted that are not the CT!
