The start is at the top of Monument Peak, however, this trail can also be ridden in the opposite direction. That said, descending it is the most fun!
The first third of the trail is pure flowy downhill. It is a perfectly chosen trail that utilizes natural features to create the same sense of flow that you find in purpose-built 'flow trails', without the 'built' feeling. You can just let the bike go and enjoy the ride.
This first flowy section of the trail leads you into the Wash Section, which is loose and rocky and can be a bit technical - a lot of fun! The Wash Section eventually puts you onto a fire road (aka Old Highway), take a left and look to your left for a connector trail that goes up the hill. This is one of the few intersections that's not really marked. You'll need to hike your bike up the first part, but the grade mellows out, and soon enough you're going back down the hill.
From here, there is more fun and fast downhill, and there are a few other trails that come into Monument Peak, but you can just follow the trail down. It's fun because it feels like it goes on forever.
You'll eventually reach an intersection where Ridge Trail
, Cascade Trail
, and Monument Peak Trail all converge. You can take a right where Cascade and Monument Peak merge for 0.3 miles, and you'll want to stay straight when they split in order to reach the Monument Peak Trailhead.
