High Plains Trail

Trail Meter: 

High Plains Trail is a great addition to the Marshall Valley trail network. It is a nice long segment of trail with fun flowing singletrack. This trail can be run as an out and back, or as part of the Dirty Bismarck loop. From the Greenbelt Plateau trailhead, the trail starts by gently going down through some short rock sections. Don't worry, these are not very technical. They will just bounce you around a little. After you cross a few gates and a bridge, you start your climbing to the end. The climbing is of a nice grade, not too steep! It includes some brief breaks in the climb as well. As you crest the last hill, you'll see the end at a gate and small parking area. If you want to continue on to Superior, go through the gate and turn right onto Coalton Trail. This area does fairly well over the winter, but can be deceiving. The muddy spots are usually hidden from the road and can be very sticky and fragile. Please make sure you check the trail meter! If you are headed back to the Greenbelt Plateau trailhead, get ready for some nice gentle downhill almost all the way back. In the summer, this trail can get HOT! There is no tree cover at all, so come prepared. Also, it can get really windy out on the trail. Eldorado Canyon causes a nice funnel for the wind to flow over the trail.

I would mark this as good if it weren't for the ruts from some minor trail damage. There are also two-three SMALL muddy spots. All except for one can be easily ridden through w/out getting muddy. The last one is right at the end/beginning on the east side that would get you a bit muddy or you'd have to walk around it. So, it's 99.9% dry.

Mudddddd. 200 yard long muddy section between the bridges, snow drift over the trail in one spot. Stay away for a few more days please!
