A solid ride close to Boulder that is often ridden from town.

Michael Ahnemann

E-Bikes Unknown

Features -none-

No bikes on the Benjamin/Betasso trails on Wednesdays or Saturdays. These loops are also directional for bikes: check the signs and only ride in the indicated direction. Boulder Canyon Drive/SH 119 will be under construction through February 2021. Check for road and Boulder Canyon Trail closures before you head up.…


This is a shorter version of the Super Betasso/Benjamin ride that starts from town.

Betasso is a good but short ride close to Boulder. It's not the best ride around, but it's very popular because it can easily be ridden from town by cruising up Boulder Canyon on the bike path, and riding the steep Betasso Link Trail up to the trailhead.

It's also an easy drive to the trailhead, which has a ton of parking and a covered structure with picnic tables and grills

Need to Know

The bike directionality changes month-to-month. Please check and follow signage at the trailhead.

There can be heavy hiker traffic on this trail, and the riding direction for bikers is determined by a sign at the start of the ride. Pay attention to the ride direction, and please be courteous to hikers.


Starting from the trailhead, you'll find yourself on the Canyon Loop. The riding direction is predetermined, and indicated on signs along the trail. Pay attention to this direction and adhere to it - the trail is carefully monitored due to the extremely high traffic and its proximity to Boulder.

The Canyon Loop is a relatively quick loop (15-20 minutes) that can be ridden by most riders. It's got enough twisty singletrack and fast sections to keep expert riders entertained, but the lack of any extremely difficult moves or dangerous areas will allow intermediate riders to feel comfortable as well. Beginners might want to dismount for a tight right-hand turn on the downhill section, two stream crossings, and a couple of fairly steep (for beginners) uphill rock/root crossings, but even beginners will find that the enjoyment and beauty outweigh the frustrations by far.

The trail surface is dry, hard-packed dirt most of the way, with a short section that winds through slightly more lush forest. There are some nice views along the way, looking out over the hilly terrain of the foothills.

New as of May 2011 is the Benjamin Loop, which starts as a spur off of the farthest point on the Canyon Loop. This new trail was built by large groups of volunteers, and features significantly more interesting terrain than the Canyon Loop. This trail winds through thick forest, and in places is cut right into the side of rock faces that required major engineering feats to build.

The new trail flows very well, and offers a nice 4 mile addition to the original trail.

If you're still feeling fresh after one loop, do a couple more, and throw some burgers on the grill back at the trailhead when you're done.

Many Boulder riders choose to cruise up the Boulder Canyon bike path along Canyon road (119). The path eventually dead-ends and forces you onto the road, and you'll ride a quick 1/2 mile section of road with ample shoulders until you get to a small trailhead on the North side of the road. From there, you can ride up the steep Betasso Link Trail to join the Canyon Loop.

History & Background

The area near Betasso preserve called Orodell was a small mining town in the late 1800's but was completely destroyed by wildfire in 1894. The mining operations there never recovered, but the land was homesteaded in the early 1900's, and in 1915 Steve Betasso, a local miner, purchased a small ranch here. The Betasso family expanded the ranch through proceeds from their lucrative mining operations, and In 1976, Boulder County purchased 712 acres of the ranch from Ernie Betasso, one of Steve's sons. Ernie, worked with Boulder County Parks and Open Space department until the early 80's to ensure that others could enjoy the land that his family enjoyed for many years. Boulder County purchased additional land in 2007, and this open space area now includes nearly 1200 acres of land for the public to enjoy.

When taking Benjamin loop, if you go left at the Benjamin loop itself, instead of right, the DH is way more fun thru trees. Not as fast tho 7.4mi

Nice trail for an easy ride in the front range, maybe as easy as it gets anyway. Still loads of fun to ride. Little bit of climbing, some really fast, fun downhill and lots of flowy trail. Trails are well signed and can be a little busy. Nothing really technical. Some great scenery. Sep 27, 2015
One of my favorite trails. It's fun and flowy, with some rock here and there. you're in the forest the whole time. Pretty cool over all. Jul 11, 2017
Great place to ride!! This is about as flows as the front range gets. The climbs are designed to be gradual and fun too. The views are excellent. Look for arrow telling you which way to ride. Sep 6, 2017
