Trail Conditions

Muddy Trail Conditions Meter
Dry Trails. Have fun!
Trails are muddy/wet in spots. Travel through the mud, not around it.
Trails have long, continuous areas of mud. Severe resource damage is likely. TRAIL USE IS DISCOURAGED!

NEW FEATURE! Users can now edit many trails at once! Login to the website then look for this button below - just click it, type in comments for the trails you rode, then click Save. That's it.


If you want to know if the trail's in great shape today, or find out what construction is going on, or which outdoor festival has ganked your favorite trail for the day, this is the place to check it out! We have a convenient system for you to quickly see if the trail you are thinking of is dry right now.


Just like our friends at Boulder County Parks and Open Space, Boulder Mountainbike Alliance describes trail conditions using a meter. Even better than the trail meter, the trail-specific comments and the trail news feed tell you what's going on and how it's going to affect your ride!


If you have some conditions to report, please let everyone know what you observed! Simply click "Edit Trail Condition" next to any trail your were just at, or "Edit Multiple Trails" if you did a big ride, and change it to reflect the conditions!

East Boulder Trail (White Rocks)
Closed
Due to repairs to the east dam at Ertl Pond (and the trail over the dam), the East Boulder White Rocks Trail is closed from Valmont Rd north to, and including, the Boulder Creek Bridge. Construction is expected to last two weeks, but is weather-dependent and may last longer. East Boulder White Rocks Trail remains open as an out-and-back from East Boulder Gunbarrel Trail south to Boulder Creek. The Boulder Creek bridge remains closed due to flooding damage. Repairs on that project are expected later in 2016. Trail closure information can be found at: https://bouldercolorado.gov/osmp/temporary-closures 141 days, 13 hours, 12 minutes 389

Riding uphill from Peaceful Valley campground trailhead, first 50% is mostly rideable, then soft hike-a-bike up to Coney Flats Road junction. Didn't ride downhill, but I can't imagine that upper section is much easier going back down. 78 days, 12 hours, 38 minutes 394
Coney Flats Road
Good
Great conditions up to the bike/drive and hike/ski junction at ~1.5 miles. Doesn't look like anyone has broken trail on the bike/drive section above that in quite a while, and wasn't rideable. 78 days, 12 hours, 36 minutes 395
505 Road
Fair
Trail was dry until probably 9500-9600 feet. After this point, the trail had a number of snow drifts that ranged from 2-6 feet tall. All were walk-able, but the going was not pleasant. Lots of water at the top by Caribou. Although one could ride down the road if they didn't mind getting a little wet, its probably best to give this one a bit more time. 350 days, 11 hours, 9 minutes 396
