A great ride starting at the entrance of Mill Mountain Park. Fairly wide singletrack followed by a super fast greenway descent transitioning into a long, healthy singletrack climb back to the start point.
Park in the pull-off just before the entrance to the Park. Cross the entrance to the park to the 4-way trailhead just in the woods. Go straight at the intersection and enjoy the ride. It's a little bumpy and the switchback is tricky, but once you're past that you can open it up a bit.
On the greenway heading down you can get up some serious speed but watch out for cars or other bikers coming up.
Just before the switchback of the greenway, head into the driveway in front of you and catch Monument
trail just off to the right. It's a long, steady climb from here but well worth it in the end because of the nice (but short), sweeping descent back to your vehicle.
