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!
