Colorado Trail Explorer

super useful, thank you.

UPDATE Oct 2026: now I cannot get any of the .gpx file to open in Garmin at all :'( Not a Garmin issue since other gpx files load ok I love this app, how much information is about the trails, making my own maps, etc.! I've recently been having an issue though where I create a trail, export the .gpx file to Google drive, open it in Garmin Connect, and the trail stops about 50% of the way through. So a 6 mile trail created here only imports the first 3 miles when transferring it to Garmin.
