Take Highway 44 west of Rapid City. After Hisega but before Johnson Siding, turn right on Log Porch Road, drive about a quarter of mile back on the dirt road to a closed gate. (Private home located here, be careful where you park.) From the gate, bike about 1 miles up the dirt road. You'll pass a pond on the right. A third mile from the pond, turn left on a small singletrack trail marked with an orange trail marker. Pass through the barbed-wire gate (be sure to close), take a left at the Y in the trail when you see the bones tacked on a tree, thats the start of the Bone Collector.
There are many fun freestyle sections with features for all skill levels. Riders can choose to take drops that reach several feet in height, steep rocky descents, and log rides. Beginner and intermediate riders need not worry, as there are plenty of other smaller features to ride, as well as ride-arounds.
