About Spearfish Creek
Flowing through the dramatic limestone walls of Spearfish Canyon, this is the crown jewel of Black Hills fly fishing. Cold, clear water tumbles past 1,000-foot canyon walls for miles of accessible public water. The canyon setting creates its own microclimate — consistently cooler than surrounding plains — keeping trout comfortable year-round. An iconic Black Hills experience that rivals any canyon trout stream in the West.
