What to see from omaha to yellow stone
Good suggestions by RosalieAnn! I would also add, after that long drive to reach Yellowstone, be sure not to miss Grand Teton National Park and Jackson (Wyoming) which sit just south of Yellowstone. Stop at Jackson Lake Lodge for a meal or just to browse the resort and admire the views. If you enjoy museums and wildlife, The National Museum of Wildlife Art is definitely worth a visit.
Mentioned in this answer:
I would go through South Dakota and visit Sioux City, Wall (of the Wall Drugstores), Devils Tower, the Badlands, Rapid City, the Black Hills, and Deadwood. Then in Wyoming, Little Bighorn, and Cody right outside of Yellowstone.
