Heading west on Rt 16 from Custer, SD to Newcastle, WY is hill country with tall pines and rocky outcroppings. As you approach Spearfish, SD, you'll travel the Spearfish Canyon Road which is one sweeping curve after another with high bluffs covered in pines. Rt 24 from Belle Fourche, SD to Hulett, WY is quite flat and not very scenic, but the road has some hills and curves.

This scenic drive has towns spaced out along the way but I didn't stop at many of them and overall it's a pretty rural scenic drive. There are enough towns however to keep you fed and your gas tank full.

I didn't stop anywhere until I got to the end where I visited Devils Tower National Monument. Ever since seeing the Movie "Close Encounters of the Third Kind" I've always wanted to see and visit this unique place and I'm glad I did. It is something to see in person and I enjoyed the hike around the structure. Highly recommend you don't pass up the chance to visit the park.
