Spearfish Canyon / Roughlock Falls Nature Area
Operated by SD Dept. of Game, Fish & Parks, there are shady picnic facilities and restrooms, along with trails, catwalks and amazingly designed viewing nodes. A popular destination for decades, the newly-improved walkways offer easy access to this wonderland. It is also known as one of the few places in where one can view the American Dipper, a rare bird that can both walk and swim under the cool, flowing waters.
Roughlock Falls is a day use area only; no overnight camping. Park entrance is not required.
