Pine Grove is a nice campground to beat the Phoenix heat in the summer. Some sites are pretty private, while others are not. Our kids enjoyed playing in the meadows, catching bugs, and riding their bikes around the campground. But other than that, there's not a whole lot else to do. It's a quiet base camp near Flagstaff and the activities there. But we enjoyed the relaxing days at camp. We went in late September and the daytime temps were perfect but the nights were pretty chilly for us Phoenix desert rats. The flush toilets and showers were a nice convenience.
We camp here with a group and reserve the entire D loop. It is a great little campground with large campsites. Many sites have two tent pads. The park hosts are friendly and keep the vault toilets very clean. They don't smell like vault toilets at all. There's lots of shade, but not a lot of foliage between the sites for privacy. If you're looking for seclusion, this may not be the place for you. But it's definitely a quiet campground, and we enjoy our time here with friends. They have a little snack shack where you can but burgers and snacks, even giant snow cones. Bring a fishing pole and a kayak or raft to enjoy the lake. You can't swim in the lake, but our kids love catching frogs and crawdads. To get there, if you're coming from Flagstaff, don't take the exit before Williams like Google will try to take you. Those dirt roads are often flooded, especially during monsoon season where they are impassable. Go all the way into Williams and come in from that route. The roads are MUCH better.
