The trip in short
Pick up the camper in Salt Lake City and drive north past Idaho Falls to Yellowstone. Three nights at the west entrance for Old Faithful and Grand Prismatic Spring, two at Canyon for the waterfalls and the bison of Hayden Valley. Then south to Grand Teton: three nights near Jenny Lake, with the mountains reflected in the water. One of the camper trips; by car, with hotels: Yellowstone and Grand Teton.
