Custer State Park
The diversity of Custer State Park is really phenomenal! Starting with the "Pig Tail" bridges, allowing you to drop great altitudes in VERY short distances to the one vehicle tunnels blasted through the granite mountains the drive is a real hoot... not to mention a "white knuckler" at times. You drop from the higher altitudes where one can see Rushmore in the distance to the plains that are populated with Prong Horn, Buffalo, prairie dogs and the infamous Burro "Panhandlers" of the park. Continuing North, one begins climbing again through more "one vehicle" tunnels to the "the eye of the needle" rock. As you exit the Park, one passes Sylvan lake and Lodge prior to returning to civilization and "normal" roads. The Sylvan Lodeg does a great Buffalo burger if you're looking for a break from the long drive!
