Colorado Trail Explorer Reviews
Best app for exploring Colorado
I love this app, I use it any time I want to go for a walk, hike, or off road adventure. I lament hiking in any other state because they don’t have an equivalent. It would be improved by having a CarPlay app as well, there are many roads on this app and it would be useful to see the map in my vehicle I swear this used to be a feature, but being able to double tap and slide to zoom the map is such a boon for one handed use. Would be great if this were (re)implemented!
Wildly Inaccurate
This app needs it mapping updated terribly. Hiking trails that have been opened or closed in the last five years have not been updated. Forest service roads from the last twenty years are not updated. Some areas have been sold to private citizens so using this app you will find yourself trespassing or having to turn around without completing a trail. Seasonal closures are also wildly inaccurate. If this is a state ran app then this is why the government needs less control. Some features are awesome like planning your route, elevation change and more accurate distances than AllTrails. Yet the apps shortcomings are aggravating and dangerous to say the least.
Best app by far
I’ve tried them all, this is the clear winner and it’s free. I wish other states would add in this this but thankfully 99 percent of my hiking is in Colorado.
Could the developers add game unit, private land, and previous wild fire layers? That is the only thing this app is missing but even without this, this is the best app I’ve ever used and I’ve paid for most the others. Good work devs!
Please make a Garmin friendly app!
I would really like to use the new Garmin watches for a GPS on OHV and single track trails for a quick glance rather than stopping to pull out a phone. Only way this app could get better in my opinion.
For me, a necessity
I love this app. Lets you make notes about what you encounter, lets you see national forest/park boundaries, record your hikes/drives/etc… I use it all the time and like that the info is “from the horse’s mouth” (from the state itself, not from a 3rd party). Just super well done. I also appreciate the recently added feature of being able to trim your recordings in the event you forget to stop it before you drive back from a hike.
Great app
This is such a good app and better than paid ones like Rever for motorcycle riding, in a perfect world it will soon work with apple carplay
Very useful
This is been a great app. It save me a few times when I was heading the wrong direction of a trail. Haven’t had any problems.
Would love it. If it was, apple watch compatible just got one and this map definitely needs to be on the Apple watch, especially out dirt biking. It would be amazing to be able to just look down at my wrist instead of having to pull out my phone or use the phone mount. Also would be really cool if you could sync up the group of people you’re riding with so you could see each other on the map. I understand that might require everybody to have cell phone service but could potentially be really cool feature specially if somehow you could have an off-line feature but could see where your friends are !
Slick interface, but lacking in up to date info
This app is being promoted as a better solution than crowd-sourced options but it really isn’t. Popular hikes have no information and some shows trails starting from closed/private land trailheads that are likely to get your car towed or at least ticketed. So it is not more accurate than crowd sourced, and it has less information. Only a few “featured hikes” have detailed information and photos. I have not actually found a user trip report yet, so it does not appear that they are getting much help, and they don’t even have all the state parks as featured. So meh.
Love this app
I use it all the time when hiking, makes way finding trails with multiple intersections. Used it a lot when off-roading as well since you can download the map for offline use. Very handy and a must have for any Coloradian. Can’t seem to get my password reset though…
Ok but mileage tracking seems off
App is okay but Trail recording distance seems off. Distance reported by this app is more than reported in AllTrails and the Apple Watch activity tracking which match with each other in comparison.
