Benjamin Loop

Trail Meter: 

The Benjamin Loop singletrack opened on May 17, 2011, and in the process doubled the amount of trail at Betasso. It's a loop, connected by a short stem to the current Canyon Loop, and also to Foumile Road via the Fourmile Link Trail.

This is a swoopy, flowy, gorgeous trail, much like the Canyon Loop. The trail twists and turns, with moderate climbs no matter which direction you're traveling. It's a hoot, and is especially fun when combined with the other trails in this park.

The Benjamin Loop is possible due to open space purchases by Boulder County Parks and Open Space (BCPOS). After acquiring 400 acres to the north and west of Betasso Preserve, BCPOS decided to build an additional 4 or so miles of trail that connect to the Canyon Loop Trail, and the Benjamin Loop was born.  Whenever you see some County staff on the trails, thank them for building this awesome shared use trail!

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.
  • Trail direction changes on the 15th of the month

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

From bracyknight via Twitter: #boco_trails Betasso Canyon Loop is good for snow biking on Monday. Hard pack and fun. Benjamin is a bit slushy/soft

Fair for snow biking. Trail poorly packed, but getting better. Some slushy spots, but not bad

Trail condition updated to Poor.

Trail condition updated to Good.

not ridable... will only do damage and would not be fun anyway!

Loops are no go till LATE Saturday or Sunday most likely according to BCPOS staff.

Trail Meter: Poor»Fair

trail is muddy in places, dry in places, bits of snow leftover from the last storm. being mostly decomposed granite, it wasn't too bad today.

From RangerFowler via Twitter: Betasso lots plowed. Snow is going fast, rocks showing through on trail. Blue diamonds mark the Canyon Loop Trail. #boco_trails

big storm = deep snow, please update this condition when you use the trail, thanks!

Half snow packed, half dirt. All rideable. Be careful on the snow/ice portions.
