An interesting short stop right off the main road in which you get to explore the Arizona landscape for dinosaur footprints. It's just a few miles west of Tuba City, about an hour east of of the Grand Canyon.
The attraction is free. There is no official entity running this attraction. Locals offer to give a tour for tips. Tours can be as short as 10 minutes to an hour. I'm not sure how accurate some of the information may be, as the tours are not guided by professionals.
Native American jewelry and artisan-work is sold nearby. You can support the local economy and buy some cool jewelry for cheap.
Overall, I think it's really cool to roam the landscape and find dinosaur footprints. Definitely worth a stop.
