Westbound drivers have it the easiest—simply follow the well-signed Historic Route 66 west from Kingman, exit 44 off I-40. From the west heading east, take exit 1 on the Arizona side of the river, then head north. Whichever way you go, you can’t avoid the steep hills that lead to Oatman (elev. 2,700 feet), an odd mix of ghost town and tourist draw that’s one of the top stops along Route 66.
