Cedar Pass, Badlands National Park
Badlands National Park is a short drive from The Black Hills.
When coming from the Black Hills, The Traveling Morgans recommend you approach from the south (SD Highway 44) so you can see "the wall" that gave Wall SD its name. Coming in the Cedar Pass Entrance, you will find yourself face to face with "The Wall" and the road climbing up Cedar Pass.
