Most people think the only way to get to the bottom of the Grand Canyon is either by hiking or pack mule.
But, as the Arizona Republic reports, you can actually drive into the canyon, via Diamond Creek Road in the Hualapai Indian reservation. And the way to get to that road is via old Route 66 through Peach Springs.
Here’s another site about the road to the Grand Canyon.
While you’re at it, you can read about other attractions in the Peach Springs area, including the Route 66 standbys Grand Canyon Caverns and Hackberry General Store.
I took that trip in April of 1971 with a friend and his dad, in a 4 wheel drive pickup . . . I don’t remember driving in the creek, but it was a long time ago. There were ramadas and campsites at the river then, but we didn’t stay long; we unloaded a 3 man raft & took a wonderful 2 day trip down to Lake Mead. Beautiful. I’ve never forgotten that long weekend.
