The greatest hits — Iron Mountain Road, Mount Rushmore, Needles Highway and Crazy Horse Memorial in one big day.
Intermediate to advanced. You're stringing Iron Mountain and the Needles together — hours of tight, technical riding. Not a first-day-off-the-lot loop.
Fuel in Sturgis, again in Keystone or Custer mid-loop, one more before Sturgis if you push it. Two park entry fees.
Alpine Inn in Hill City for their famous filet mignon dinner; Powder House Lodge in Keystone for lunch.
Full-day ride. Roll out at 7am, back by dinner. Avoid Sundays in August — traffic peaks.
