Fat tires were created for adventures like this 109-mile rail trail in South Dakota’s Black Hills, known by the Lakota natives as Paha Sapa and “the heart of everything that is.” It’s a movable feast for the eyes as you pass ponderosa pine forests, prairie lands, rugged mountain terrain, grazing cattle, swimmable creeks, and rocky canyons, feeling with every pedal stroke that you’re traveling on sacred ground. Though the route peaks at 6,100 feet of elevation, it rarely exceeds a four percent grade [Lauren Matison, "Ten Best Car-Free Bike Paths in the USA," Bicycling, 2014.09].
Contrary to Woster's report, the cycling magazine doesn't explicitly rank the Mickelson Trail the best of the best; the Mickelson is just the first item to click in a list that includes the Trail of the Coeur d'Alenes in Idaho, John D. Rockefeller Jr.'s Carriage Trails in Maine, and (closest to South Dakota) the Katy Trail in Missouri. But I'll vouch for the Mickelson Trail's visual stunningness and geological and ecological diversity. It's the best bike ride I've ever had, solo and with my family.
