If you are in Yellowstone National Park and want to travel to Mount Rushmore in South Dakota, I suggest an overnight stop in Cody, Wyoming. Buffalo Bill’s hometown has everything you could wish for in an authentic Western town including American Indians, cowboys, horses, and rodeos. Cody was my hands-down favorite stop outside the National Parks on a 14 day trip from Seattle to South Dakota.
To drive from East Yellowstone to Cody take the Scenic Byway of Highway 20 through the Wapiti Valley. President Theodore Roosevelt called this stretch of highway the “fifty most beautiful miles in America” and I concur.
We drove this route a few years ago and the views and sights never end. At one point we saw about 50 wild horses running as a pack in a field about 20 feet from our vehicle. This drive is definitely a white knuckles type of journey because you are way up on a mountain pass and the drop down to the river is very deep. I would not do it again but am forever grateful that we experienced this special place.
