I am trying to plan a trip in September for 3 weeks, flying into and out of Denver from UK. We want to go North to mount Rushmore, then, roughly, across to West Thumb in Yellowstone, then back to Denver via The Tetons. (I'm aware that Yellowstone is already partly booked up.)
My husband is 70, but still a very good driver. Could anyone please help with places we must visit en route? We're happy to move on each day, unless there's something worth an extra night's stopover, until we reach Yellowstone, then stay there 3 nights, followed by 2 in Grand Teton, before returning to Denver. Any motels, lodges, ranches, things to see would all be greatly appreciated. (and where to avoid!)
Definitely don't want more than 150 miles per day once off the Interstate.
