In October 2021 I went to Peach Springs, Arizona and purchased a pass from the Hualapai Nation to traverse on a 20 mile dirt road/trail into the Grand Canyon. As far as I know, it's the only part of the Grand Canyon that you can drive all of the way to the bottom of the canyon.
The following is my review on alltrails:
First 10 miles of the trail was a washboard, well maintained wide dirt road. Next 8ish miles a little bumpier and narrower, but still passable by pretty much any vehicle. At the end of this section you'll come to a sign on your left stating you're entering Hualapai land and it'll have emergency phone numbers. On the right will be a small lot - in which you can park if you do not have a high clearance vehicle. Otherwise, in your high clearance vehicle continue on for the next mile or 2 until the end. The trail will get bumpier and there are some bigger holes and small streams to pass. At no point will 4WD be needed. I did this in a stock Wrangler with 33 inch tires. At the end is the Colorado River. There are picnic spots and port-a-potties. The river is swift here and no cove. There is a large flat area for picnics, etc.
The scenery was best those last couple of miles as you drive through the canyon.
Don't forget to stop at the Hualapai Fish and Game in downtown Peach Springs (the rock building) to get the $30 pass to drive the road. I think it's worth it. I'll definitely go back again.
The Vagablog is a combination of my wild adventures (traveling, overlanding, hiking) and tools for living a more balanced life (meditations, yoga, self care).
