Description

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.

As you ride the downhill portion you might start thinking that the ride back up will be daunting, but it's generally gradual and easy; soon you'll be back at the trailhead, thinking very seriously about doing the loop again.

In this video I ruin a ribeye steak, get harassed by my dog and drink from a steel mug. Oh, and we also go Mach Chicken thru the trees on two-wheeled wonder machines.
