Canyon Loop

Trail Meter: 

The Canyon Loop is a short but stunningly beautiful 20 minute lap.From either parking lot or the Betasso Link Trail, take the Canyon Loop Trail in the required direction. Both directions are fun and the county usually changes the required direction on the 1st of every month. You start at a high point and descend about half way before climbing back up to where you started. The trail is bench cut on a steep slope. So although the trail is technically pretty easy, it can cause problems for those with a tendency for vertigo. Most of the trail is pleasant singletrack, relatively flowy, and about 3 feet wide, but perhaps 1/4 of the loop is on the historic Betasso Ranch road. There's an incredible overlook counterclockwise from the trailhead, less than a mile along the trail that overlooks Boulder Canyon with great views of the the University of Colorado and the city.

Important stuff you should know:

  • This trail is closed to bikes on Wednesdays and Saturdays
  • This trail has a required direction for bike traffic at all times (look for the arrow when you get on the trail)
  • Trail direction changes on the 1st of the month

Please obey these rules and BMA will continue to work with BCPOS to make the system work better.

Betasso Preserve is one of the few places to get in a mountain bike ride from town without the use of a car. Ride up the Boulder Creek Path, which goes through town and up Boulder Canyon to the intersection with Fourmile Canyon. Then you have to jockey with traffic on Boulder Canyon Drive (Highway 119) to the Betasso Link Trail, or you can head up Fourmile Canyon to the Fourmile Connector Trail.

Trail Meter: Poor»Good

Trail is good to ride. Enjoy!

Lots of rain and snow today. Will need several good days of sun.

Running CCW. Awesome dirt on the descent. The climb out got pretty rutted out with people riding after last week's snow, but it's all dry now.

4 inches of snow

Snow! (so great if you have a fat bike!) And soon to be very muddy.

Trail Meter: Fair»Good

Hardly any mud left at all, beautiful riding!

Still some muddy, sloppy spots with standing water, especially on the eastern climb. Otherwise good.

Mud/Snow in a few spots but 80% of it is great

alternating between summer dry and a few small sections of mud, except less snow/ice as its continuously melting. Trails are super sensitive and will easily widen in these conditions, so ride through not around!!
Patches of mud and ice - maybe 5-7 of them. As long as you aren't a poseur and ride through the mud like a a real mountain biker, it's good riding.
