Colorado Trail Explorer app reviews

  • Great hiking app for Colorado. 5/5

    By mudfoot04
    I have used premium hiking apps that charge an annual fee and COTREX does the job every bit as well as the premium apps. COTREX is free! If you hike, bike, or just enjoy moving around in the great Colorado outdoors this is a very helpful app to have on your phone.
  • By far the best 5/5

    By blaskoa
    There is no question this is the best map for Colorado. They have trails listed that no other app has.
  • New update is AWFUL 1/5

    By hilda274
    Please fix!! It doesn’t track with the GPS correctly anymore, it is not as intuitive, and just all around a terrible app now! :( I used to recommend it to EVERYONE riding or hiking in Colorado, and now I can’t. It quits halfway through recording and does not record correct mileage. I did a 9 mile round to hike that COTREX said was 12 miles. Wth happened guys?!
  • Go to app 4/5

    By ronpar
    Works well and consolidates information from multiple agencies in one location. The new interface caught me by surprise on my most recent hike, but I was able to figure it out on the fly. It looks like the newest update introduced a bug which makes the space bar operationally non-functional in the description field of a trip report. Looks like it enters and erases. The last couple of updates have introduced an issue where the app complains if I’m taking pictures too long. It would be nice if that was changed somehow..
  • I used to love this app… 2/5

    By Ida's Mom
    Okay, so after I wrote the scathing review, I found the red button - which does not show up on opening page, you must press the directional arrow in lower menu bar to find it - & recorded my walks. Two days in a row the same 5.6 mile trail I’ve walked for two years is now 7.1 & 7.2 miles respectively. I am comparing this to another mapping app which has always read within 0.2 miles of COTREX, so I know the original mileage was correct. Much as I’d like to brag about walking 7 miles daily before breakfast, that’s just not accurate. I always carry my phone in side pants pocket so there is no chance of extra movement being the sudden difference. Please fix this!!! —————— …until the recent update that removed the Record A Trip feature. I hike daily with my dog near our home & thus am familiar with the official trails. We often go off trail through the woods, sometimes using COTREX to stay oriented & always to keep track of our route. Now all that’s available is the Create Route feature which makes assumptions about where I want to go based on input of only 2 location points, completely useless. After I transfer my 190 recorded trips to my computer, I’ll be deleting this app. So disappointed!
  • Updated: Must keep phone open to use?!? 5/5

    By tbpk
    Update: Bug below was fixed in latest release and now app works great. I tried to record a trip when I was trail riding on my horse. I started the trip, then left the app running but turned off my phone screen to put it in my pocket. When I finished my ride, I opened my phone and the app said my trip had been paused right after starting because the screen was off. Who wants to hold their phone and keep the screen active for a whole trail ride, hike, bike ride, etc? Can you really not record a trip unless the screen stays active?
  • Colorado is one step ahead 5/5

    By FedericoVenier
    The other states should learn from us!!!!
  • Great app 4/5

    By MM9046
    Great app for hiking in CO—trip planning and for use on the trail with the ability to download tiles and use offline. The snap-to-trail measuring is great, though I wish it worked on cross country ski routes. It seems to only work for hiking trails. Other than that, fantastic!
  • Great App Overall 3/5

    By ZeviZ
    This is my go to app when hiking and dirt biking the forest roads.....but please make wide screen compatible!!
  • Best app ever 5/5

    By AutoPDR
    One of the best apps I used! Easy to ride with it. It would be even better if you can add navigation option.
  • Excellent but needs features 4/5

    By Ratings feature needed
    Wonderful app but PLEEEEEASE add overlay with colored trail difficulty levels that match actual trail maps (black, blue green). Thanks!!!!
  • No app support 5/5

    By JamesinDen
    COTREX is great and functions really well offline, but there is zero app support and a mirage of bugs to report/fix. I’m happy to help fix these...
  • Great potential, but difficult to use 2/5

    By IronCupcake3000
    I was so excited when I first stared using the app, but I am now feeling frustrated and find myself using All Trails instead. Creating a custom route is tricky, and I accidentally deleted several before I got the hang of it. I also can't seem to turn a recorded route into a custom route. I just want a place to store all of the trails I've hiked and liked, but the way the categories are broken down is too granular and confusing. If this app were simplified and streamlined, it would be amazing!
  • Great app 4/5

    By 10Rubicon
    This is an awesome app for off-roading in Colorado. Nice to see your location so you know were you are on a trail. Can this app be made to use on car play so I don’t have to look at my phone screen to see the map? That upgrade alone to me would make this app complete.
  • Needs updating 1/5

    By codeshifter
    This app was amazing until I updated to the new IOS and now it won’t even open. Please fix the issue so I can use it again.
  • The best app for any outdoors person in Colorado! 5/5

    By K_v_K
    If you like doing any outdoor activity in Colorado this is the only app to use.
  • Great App that doesn’t work. 2/5

    By B-wils
    Every time I try to use the filter option it errors out. Can’t get any trails using filters or searching for just a basic “kid-friendly” trail.
  • Trails app 5/5

    By Violettsareblue
    I love this app! I’ve used it multiple times out on hiking trips. I’ve discovered trails I had no idea were there from studying the map in various locations in the state. Wish they had apps like this for other states as well.
  • Message to app developers 4/5

    By jahapruce
    Hey it’s a good app thanks for making it. I would like to add a suggestion for the app. I am wondering if the team could add a feature that shows private land borders on the map. Also would like to know if the back country camp sites could be listed as well. Thanks again and take care app developers
  • Crashes 1/5

    By Almost13ranch
    With the new update, when you zoom in on the map the app closes.
  • Best moving map for ATV 5/5

    By adeleblack
    Love this app! The trail descriptions are great (thanks for using names and not just trail numbers). I use this on an old ruggedized iPad mounted to my ATV. Once I figured out how to keep the screen active when plugged in to power it works fabulous (settings / battery/display & brightness/auto lock/never). My only knock, and it is a tiny one, when tracking a route, the ATV trail tracking is brown. I would like to be able to select colors for specific rides as brown is really hard to see overlaid on the satellite topo view especially in bright sunlight. Other than that this is a must have app for Colorado trails.
  • So far so good! 5/5

    By WaldoF16
    Did one ride (OHV 50+) to the Top of Argentine Pass. Trails were right on! GPS seems very precise. One thing I haven’t figured out is why some trails are Orange and others are Green (Can’t find a map legend in the program).
  • Thank you!! 5/5

    By Musician76
    Thank you for the app!! We’re new to Colorado and this makes finding awesome trials in the area so easy. It’s easy to use and there’s an option to download locations just in case you lose reception. Lots of other cool stuff too like receiving achievement badges for completing cool challenges. Thank you so much!! 🙏
  • Perfect app 4/5

    By Chriz2019
    Overall this is a perfect app to go hiking. I gave 4 stars because I am missing some features and some technical issues - current location icon disappears from time to time and appears again after a restart of the app - direction is not shown on the current location icon and map should turn ( map is fixed north up) an option would be great
  • Update: Awesome App! 5/5

    By Patrick1357
    Awesome app. Soooo much content. Super useful if you like hiking, especially when you’re on the road. I just love it. Developers are on the ball, too: in 24 hours, they fixed a bug that prevented the app from working on iPhones. Keep up the great work, developer guys and gals!
  • COTREX app 4/5

    By JRH10101
    While the app is pretty decent once you get the hang of it, it still isn’t no onX. I like that it can track you but it get very annoying having to turn my screen back on every couple of minutes while I’m trail riding taking my eyes off the road and a hand off the wheel which can always be dangerous. I would love to see a new feature where the phone screen doesn’t time out and shut off while you are using the app.
  • Good nav app! 4/5

    By mtnbkrmatt
    First off, I live in Colorado. I like this app so much, that I bought a used iPhone and hard mounted it to the handlebar on my dirtbike. It’s awesome for trail riding. I’ve used it to find new(to me) trails in my area. The only thing I would like to see added is a “4wd” or “Jeep” tab. There are tons of roads that are closed to OHVs, but open to vehicle/4wd traffic.
  • Comprehensive but has problems 3/5

    By girdbidbj
    When I am on the trail, I need to power my phone off then back on every time I want to use the app. If I only want to see the map of the trail I can just leave my phone on and open the app when I need it. But if I want to see the blue dot of where I am on the trail, I have to stand there doing the powering off then on thing. I have an iPhone XR, so it isn’t a matter of old technology, and these are trails with plenty of 4G bars. That said, I love how this includes every conceivable trail in the state.
  • Guidance doesn’t work on iPhone 4/5

    By steveArrivo
    The app is decent but significant differences between desktop and mobile. We’ve tried it for motorcycle guidance and the screen doesn’t update location or stay on. That’s useless. Hiking - I have trail open and follow along but not in guidance mode since it doesn’t work.
  • Recording trips 4/5

    By 29modelaphoenix
    A great app except you should be able to record a trip using off-line maps that have been downloaded. Having to login is unacceptable to me.
  • Awesome app 5/5

    By jdritzer
    Very helpful in the backcountry
  • So far not meeting expectations 3/5

    By rhinoviper69
    I just downloaded and signed up for the app. I was excited to find the custom route feature! Unfortunately, it took a long time to figure out how to tag someone, then the person I tagged is getting an error when clicking the link I sent via text. I’ll keep poking around, but sharing/tagging other users is a differentiating feature that I was truly looking forward to using.
  • Impressive 5/5

    By Catnip trip
    This app is so great! I just made a route for a backpacking trip by tapping points on the trails, and then saved it to my account. It includes the elevation profile, and you can download it to your phone. I don’t need any of those other apps anymore! As a front ranger, I appreciate that this app will probably help spread all of us hikers out and decrease crowding on a lot of trails by making us aware of all the options nearby. Thank you!
  • A Good Start, But Needs Better Filtering Capabilities 4/5

    By Telehound Bob 01
    I applaud the State for putting out this project. Having an app like this is long overdue. That said, I hope future iterations filter the data better. For example, when I hit the bike box, it gives suggestions for rides, but trails where no bikes are allowed are still shown. Someone traveling to Boulder, for instance, might incorrectly assume that the City’s trails on the west side allow bikes, which it does not. I also recommend using colors other than green for trails, as many folks are red green color blind and will have trouble seeing the data. Overall, thanks for a great new product, with improvements it can be five stars.
  • This is the hiking app I have always wanted! 5/5

    By Mark & Linda
    We have used this app on 4 hikes so far, and it has been fantastic! Every time the trail is vague or has multiple forks, this gives you the guidance you need. We went to a popular trailhead on the weekend that was packed. My wife joked that it looked like the security line at the airport. We used this app to find a nearby trail where we met zero other hikers in 5 miles, and the views were fantastic. It was so nice knowing exactly where you are on the trail, and knowing all the nearby trails. We also love the ability to download map blocks so you aren’t lost when there’s no cell service.
  • Good app! Great for motorcycle riders! 5/5

    By Eeve132
    EDIT: my first review was all wrong! This app has every trail you know of for moto, OHV etc. it gives you all the need to know info about it ( I like seeing if it’s a gravel road or real trail) I haven’t seen it yet on here but I still may be wrong, but it would be nice to have a feature to review the trails so people can hear if it’s in good shape, weather damaged etc. So far though this is by far the best app when it comes to being a motorcycle trail rider. It’s clear information so you know if you’re on a road=LP or trail=sticker so you won’t run into trouble.
  • So aggravating to use 1/5

    By BryanBLDR
    This app was so aggravating to use, I deleted it after 5 minutes. It is not user friendly at all. I mistyped my email address when signing up and couldn't find a place to update it. I tried to delete and recreate my account and now the account simultaneously doesn't exist and is already in use. Difficult to figure out which grids to download to get the trail you want offline. Couldn't figure out a way to make a route out of multiple trails. It's a mess.
  • Doesn’t work 1/5

    By jps6703
    Says I don’t have a internet connection when I do.
  • Been Waiting for This! 4/5

    By Locologo94
    Finally a trail navigating app that is run by the people that control the trails! I only just downloaded the app, I will update this review when I take it out and use it around the Taylor Park area. Huge props for actually having the trail names on here, instead of just the trail numbers. That one feature makes it better than the other apps that I have been using for trail navigation. One suggestion to the developers: take the community aspect of this app to the next level. Make it to where you can add friends and leave comments on each trail that can either be seen by friends only, or the public. This would enable people to warn trail goers of dangers (rockslide, fallen trees, etc.). Also make it to where you can form a group. Say you are riding with 4 other people that each have their own OHV/ATV. You could share a pin/waypoint with the whole group so that if anyone gets separated, they would know where to go. Add the ability to send a distress call, that can be seen be sent to all nearby app users as a push notification. (For example: “Ran out of gas”, or “rollover, broken leg, need help”). This app is already amazing, but also has so much more potential! Thanks devs!
  • Beauty 4/5

    By art4med
    Note: have yet to use it on-trail. The selector and trail designations seem great. I found that I am going back and forth to USFS VUM (Vehicle Use Maps) to determine if dispersed camping is allowed..... *most people will not need that, I’d love to overlay.
  • Awesome complement to my outdoor kit! 4/5

    By Mingelstead
    Excellent app! Hope to use this often. My only suggestions are to include more overlays, such as private property/land management/county assessor maps, and allow the user to drop pins that are not at the current location. Thanks for this!
  • Absolute trash 1/5

    By azsxdcfvbhj
    In case you don’t want to read the Terms of Service yourself, I’ll summarize: “Inaccurate, useless spyware.” Neither the maker of the app nor Colorado Parks and Wildlife believes the material to be accurate or useful (almost verbatim from the Terms of Service). They’ve also given themselves carte blanc “to access, read, use, preserve and disclose any information”. Seriously?! Your tax dollars at work...
  • Good start, unusable on iPad without self-rotation 5/5

    By DeaconPatrick
    Update: Developer very responsive in fixing the iPad orientation issue. Thank you! Needs to rotate to match orientation of devise. It's up-side-down on my iPad Pro w/ keyboard, so I can't use it at home for planning. Initial look is impressive though.
  • It’s upside down 3/5

    By Tadbaranddog
    I have my iPad on a stand. I have to turn it upside down to see the app, so I can’t use my stand. It won’t rotate. It’s too difficult to use the app with one hand (my other hand is forced to hold my iPad).
  • Good, but please add Trail Running as an activity. 3/5

    By JustaDrill
    Trail Running is it’s own activity segment and separate from hiking. CO is #1 state for trail runners. Often trail runners want to know what % of a trail is runnable vs technical/too rocky to run, etc. Some routes are known for their trail races. I hope it’s considered in your next update.
  • Yes 5/5

    By hskahakshekwiqvxnc
    More people need to use this app! Don’t stop updating and improving it though! Maybe some trail difficulty ratings?
  • Bravo! 5/5

    By JohnnyTranWasInnocent
    The commitment to the outdoors by the fabulous people at CPW is one of the many reasons why I love Colorado. This app is fantastic. My only suggestions would be to add an Apple Watch interface/Apple health integration. Otherwise near perfect.
