One of the only spots right outside of Grand Canyon where you can camp. Lots of space here and some fire rings set up. When I was there in mid March there wasn't a lot of people there either. I had pretty good 5G service (T-Mobile) at the opening pull off and some 4G farther back. Several big open areas close to road and then dirt road goes off in several directions which I'd believe leads to more spots.
Don't forget you are on Native Land! leave it better then you found it.
