It is old forest road, but is intermediate/difficult due to the variation of terrain. It needs to be ridden in to create a trail tread. Take the mountain bike. The mile markers on the trail and direction signage are good.
The trail head is located on highway 143 west of Robbinsville. To get there, take 143 past the Cheoah ranger station to the T intersection, turn right. Follow 143 until Santeetlah Creek is on your left. As you start going up the hill, you will come to the intersection of Snowbird Rd and Santeetlah Rd. The trailhead is in the parking lot on the right.
