NO facilities at all. No water, no trash pickup, and no toilets. Bring Everything and pack it all out. 

If there are fire restrictions, PLEASE don't light campfires. After years of drought, this place is a tinderbox. Your mistake could easily trap people further up the canyon with no way out. It is Illegal for a reason. 

The first mile is an easy dirt road, suitable for RV's and Campers.

The rest of the way is a fairly rough forest road - heavily rutted in places, with some steep drops. I wouldn't take anything but the smallest trailer back here, but it's perfect for tents. 

That being said; my AWD Subaru Outback made it there and back with no problems. 

Beautiful and cool during the summer - gorgeous stars at night.
