Quiet but busy
The trees here are very thin so you can see quite far. Many spots down this road so you can have your pick but you can see everyone. From our spot you can see 5 cars, and we are hundreds of yards apart. Otherwise it's very quiet.
Off the beaten path
Quiet spot that we had to ourselves in mid November. Room for maybe 30 but more than 12 or so would feel cramped. It was quite cold and very windy. The BEST vault toilet I have ever used! Only 4 stars because inside the loop, and outside in the surrounding area is inundated with prairie dog mounds, which is fine, but we had dogs that are supposed to be on leash as we are still in the national park here (I think) which made for interesting potty times
