John, We did not take the Oliver down Indian RTE 6 to the Colorado River. We left the trailer at Grand Canyon Caverns Inn. The Indian RTE 6 was not paved but very rocky and had a lot of washboard. Trip was 20 miles down to the River, taken One Hour to make the trip with Truck only. Also you need a permit from Hualapai Game & Fish locate in Peach Springs, AZ . The permit cost $16.27 per person. When we made to the river, an Hualapai Game official check if I had the permit.
I just made it home last Thursday. Trip duration 04-10-24 to 06-27-24.
Best Regards,
Allen
