Photos of Our Ride Through Spearfish Canyon 70th Annual Black Hills Rally & Races 2010 On Saturday, I decided to take Tanya on a ride through Spearfish Canyon. The Spearfish Canyon Scenic Byway is billed as one of the most beautiful rides in the country. We started off in Spearfish, then rode it to Deadwood, Boulder Canyon and back into Sturgis. It was kind of rainy, so I did not make as many stops as I would have if it was dry, but we enjoyed the ride thoroughly.
