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.

Fourmile Link Trail is open. Careful on the ice crossing the creek. Bridge still out. Trails at Betasso are very icy! #boco_trails

60% clear 40% snow. Tires stick to the snow, but the snow stays put. Everything's rideable and in pretty good shape

Same as Canyon Loop. 60% snow covered, 20% some snow and 20% dirt. Fun ride, snow is grippy. Will be tough to ride if it freezes over.

As of 12/24 90 % dry with some snow drifts that are melting. All rideable without causing trail damage. Good to go

Got every kind of trail condition EXCEPT mud. Dry trail, packed snow, icy spots, a drift here and there. The north facing slopes on the descent down from the top (clockwise) is a bit death defying - off camber snow drifts that make you ride like you are on a skinny while dodging tree trunks. Seriously fun if you've got the huevos!

80% dry, 20% snow/ice in north facing slopes

Friday 11/22 2pm: trails on north facing slopes have about an inch of snow... south facing slopes are clear. gr8 ride!

The loops are solid. Little bit of wash out and debris in places but it just makes the ride more challenging! It's awesome to have trails close to home open again!
