The George S. Mickelson Trail has to be one of the most beautiful trails in the US. The north end of the Mickelson starts in Deadwood, where Wild Bill Hickock and Calamity Jane are buried. A big portion of the trail runs through Black Hills National forest Land. Since the Mickelson Trail follows an old railway corridor, the steepest grade never rises above four percent. Dumont at 5700 feet, is the highest point on the trail. At a length of 114 miles, it is also one of  the longest improved trailways. There are 4 tunnels and over 100 bridges along the Mickelson Trail. Even though the Mickelson is well maintained, there are short sections which have loose gravel. So, wider tires are a big plus.
