The Centennial Trail is over 100 miles long and was built in 1989 to represent the 100th anniversary of South Dakota's statehood. This part of the trail begins at the French Creek Horse Camp Trailhead in Custer State Park and travels through a dense ponderosa pine forest in the rolling Black Hills. The route starts out on fairly level terrain for the first 1.5 miles, and then becomes a strenuous climb for the next mile. Most people will do this route as a one-way day trip with necessary vehicle arrangements, but it can also be done as an out and back. Custer State Park requires a park entrance license for each vehicle.
