  • Not reliable

    By Boulder area trail user
    This app has one job - to show which trails are open and closed in the area. Unfortunately, it does not reliably do that. Right now in the City of Boulder all Marshall Mesa area trails are closed due to mud, but the app shows them as open. This was also the case yesterday when I showed up to the Marshall Mesa trailhead with friends and found the gate closed. Also, in Boulder County the app is showing Hall Ranch open, when those trials are also closed due to mud. I was originally really excited about this app and recommend it to many people, but I will stop doing that until the app proves to be more accurate. Until then I’ll just continue to reference the agency websites directly.
  • A good start

    I’m sure this app will be changing a lot as it gets off the ground. It would be great if it had cross-country skiing as a filter, as well as ease of use, both for skiing or other uses. Also would be great if you could search for off-leash vs on-leash accessibility for dogs.
  • Avid hiker, disappointed app user

    By Eric2M
    I live here in Boulder and love open spaces. I’m out with my dog just about every day. Unfortunately, this app is severely lacking. An example - clicking a trail brings up a huge (50% of screen) overlay that covers up the actual trail. Some trails are broken into segments and require tapping through one segment at a time. Any trails is far from a great app but it is also far superior to this one. Maybe next time the dev team will consider doing live user tests to get feedback and make the app better.
  • Has promise, missing many trails

    By Toddo14
    App seems slick but borderline unusable missing so many trails. For example Skunk Canyon isn’t listed at all, Mesa Trail has scattered patches, and the Bear/NCAR road which Xcel sporadically closes isn’t listed. Noticed all that in 2 min of looking around so I imagine a lot more is missing. Hopefully they make it actually “comprehensive” like the press around the app launch claims.
  • Looks good so far...

    Looks good on a phone, but not on an iPad. Will this be improved?

    Awesome app! Runs really smooth. Has all the information I need and is up to date.
