As it's so huge, there's so much to see and do when you travel along Route 66. You could spend months truly investigating everything on the way, but if you want to see the best of the best, why not add a trip to St. Louis and the Gateway Arch to your bucket list? When you get further along, check out the Route 66 Museum in Oklahoma, and then the Petrified Forest National Park in Arizona.
This national park looks like another world and is something you definitely need to see at least once in your life. After all, the petrified wood in this park is over 225 million years old!
