This is a day use only area, but there are quite a lot of long term "campers" in the area who live in the woods nearby and use the hotspring as their bathing facilities. Expect plenty of nudity. 

The hot springs themselves are lovely. Go with a sense of humor and appreciation for the nature and you'll enjoy it.

We camped at the nearby Toketee Lake Campground which allowed us to visit the hotsprings just before sunset when it seemed quieter. It was also a smokey August because of fires, so there were fewer tourists than normal.
