14 Route 66 Attractions to See on Your Next Road Trip

Here's a good old-fashioned roadside attraction. Called the Coconino Caverns on some old maps — and later, Dinosaur Caverns — the Grand Canyon Caverns (115 Mile Marker AZ-66) are accessed by an elevator that takes you 21 stories underground. Aside from the normal cave formations, attractions below include a mummified bobcat. Outside, you'll see dinosaur replicas lining the walkway to the front door. This complex has everything: motel rooms, a restaurant, gift shop, and even an airstrip.
