Miles of fresh air, Black Hills views, and zero rush. This is your sign to slow down and take the scenic route! 🚴 Following an abandoned railroad route through the Black Hills, the Mickelson Trail is a favorite for biking, hiking, and horseback riding. The path winds across crushed limestone, gravel, and historic wooden trestles, featuring more than 100 converted railroad bridges and four rock tunnels along the way. #HiFromSD #BikeTrail #SummerActivities #BlackHills
