You follow a one way out of the trailhead to get to the loop, when you come to the fork stay right, and follow <br />
the orange markers. They are all over the place, and keep the trail well marked, there are equal amounts of <br />
ups and downs, the downs are definitely fast and fun.
Take US 16 south out of Rapid City, the same road to get to Mt. Rushmore. Follow this for about 11 miles <br /><br />out of town. Take a right at Silver Mountain Road, right after the Rockerville exits. Follow that road in for <br /><br />about 1/6 of a mile, and take the first right you can this is the Coon Hollow Trailhead. This is wear the loop <br /><br />starts. There is also a a mild downhill, course on the other side of the road, it takes a little bit of exploring.
