The trail is easy to follow. On the way down to the North St. Vrain River you will pass an old cabin and go over a few sections of sweet single track. When you get to the bottom, take a right. (You can go left and into Button Rock Preserve if you're not biking.) You can then go upstream for a couple miles to a campsite. The trail along the river is really rocky in some spots.
On a later trip, I took a trail from this campsite up a valley. It was a good aerobic climb out, with one steep climb. The trail came out on a 4x4 road, which I went right on and it went back to the trailhead.
