The road is a well maintained gravel road. There are quite a few available spots for folks with 4x4 drive or tent camping. I would NOT suggest this for larger rvs. I travel in a camper van and the spots I could use were more limited but still a few available.
Honestly, just the drive is worth it. The scenery is amazing. You’re winding down the road next to a creek (was dry when I was there) in between mountains. It’s absolutely amazing.
Zero signal. Like absolutely none.
There is a rest stop a few miles in with basic toilets. Nothing special but really nice option to have.
