Convenient, but underwhelming.
As others have mentioned, this is little more than a parking lot with fire rings and picnic tables. No frills. The pit toilets are not very well maintained. The locks are broken, they are dirty, and there is no toilet paper. There are some interesting sites just up the road that you can walk to, including some ancient petroglyphs. If you continue down the road, you will also find the Temple Mountain Townsite Camping Area which is a little nicer, but usually busier as well.
