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.

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

Trail was Pretty good except for a very few short patches of ice.

On 2-18-2016 at 4:00p, the trail was in and good. It was approximately 1% mud covered, and approximately 3% - 5% snow/ ice covered.
Also, for you roadies, the road to Ward is dry the whole way up via Lee Hill.

I have to take issue with Ranger Hartnett's post that Betasso trails are in "great shape." I rode the Canyon Loop and Benjamin Loop trails yesterday morning and there is a lot of ice that will turn to mud soon. I'm leaving the condition as "fair" because almost all terrain is "rideable" but would caution riders that the ice is dangerous and that trail damage is an issue for at least the next week.

A little ice, mostly rideable.

Dry trail for about 1/2-3/4 mile going CW, then lots of off camber snow drifts. Had one foot down for most of the loop till four mile junction, then rideable again. Not muddy just hard to stay on trail. Fat bike 4.8" tires

Mostly snow and dirt mix, you will run into ice on the areas of the trail that do not get sun.

Lots of ice on Sun 01/17, but some dry spots and good packed snow too.

condition set to Good

Good snow pack on all but south aspects where it's dry dirt. Rode it on regular tires no problem.
