Cross Country Ski and Mountain Bike

The trail starts out with a really flowy singletrack then connects up to some ATV trails. On the single track, just stay on the main trail. There are several little splits several you can take that all come back together. If it splits off hard, stay on the main trail. These other routes aren't really optional challenges, just different routes. At the end of the singletrack section, there'll be a cattle guard and you'll come to a 'T'. Go left, then immesiately right. The trail is mostly downhill but there are a couple of pretty good climbs at this point. There are a lot of junctions but if you keep right at all of them from here, you'll make it out just fine. There are several small jumps on the trail. All in all, it's a pretty flowy track with some great berms. Don't run into any cows and go fast through the thistle patch near the top (it'll hurt less that way).

Never modify trail features. Ride trails when they're dry enough that you won't leave ruts. Speak up when you see others on the trail and always yield to hikers, horses, and others coming uphill. Always ride on the established trail.

Head up into Kelly Canyon past the ski resort, then take a left at the first major fork you see. Continue for another 3 miles until you see a large parking area on your right just before you turn right down a hill. You'll want a shuttle vehicle at the bottom of the hill. To get there, just continue right at that same fork after the ski hill. That road will continue down by the river.
