After getting your shuttle to the starting point mapped here, the ride begins on an old forest road that narrows down to doubletrack in many places. You'll pedal this old road for miles, meaning that this isn't a top-tier singletrack ride the entire way.

Eventually, the forest road gives way to a wide singletrack that consistently narrows down until you're finally pedaling a true trail. Unfortunately, as the trail traverses the ridge and then descends a section of steep hillside, the trail (despite being a legal, designated trail) disappears at times, and can be almost impossible to follow without a GPS track.

Eventually, North Boundary reaches a junction with the Devisadero Peak Loop, leading into the final, rewarding descent.

The Devisadero Peak descent is rideable in the downhill direction, but some sections will still test even advanced mountain bikers. There are some respectable ledge drops, brutal rock gardens, slab rock rolls, loose rolling rocks, and plenty of sharp switchbacked corners. The sightlines are quite good into most of the features, allowing riders who are unfamiliar with the area to rail through even the biggest features. Still, if some features seem non-obvious, you can always hike back up and spend some time sessioning. For the amount of work that you put into getting here, it's best to savor the descent, as it's unfortunately over all too quickly.

This trail is also very popular with hikers, so be sure to ride heads-up. That said, enjoy the rip down the mountain—you've earned it!
