We stayed at Headwaters Campground last month & we enjoyed our stay there. It's a very good location if you are wanting to explore both Yellowstone & the Tetons. The bathrooms/showers were sufficient, nothing fancy but clean & adequate. We also used the laundry which was also adequate. We would stay there again.

Although our visit was disturbed by a man using the women's bathroom (while women were present showering, using the sink, and using the toilets), security took our complaint very seriously and increased patrols, looking for the creepy perpetrator. Park Rangers were contacted, too, and quickly apprehended the man in question, providing no-nonsense tips on how a woman/girl can keep herself safe in such circumstances.
The cabin was clean and very comfortable. All around a great place to stay!

Site 317 is right next to the bathroom and the tent campers outdoor sink for doing dishes. Also, seems like the wifi is best near the bathroom. Constant parade of people. One morning I opened the door to my trailer only to lock eyes with a woman standing 3 feet from my door. I laughed at her rudeness and she replied, “Don’t mind me I’m just trying to get the wifi.” The speed limit is 10 miles an hour when it should be 5. Management has not re-graveled the roads in a long time. I ate dust for 3 days. We were supposed to stay for 7 nights I left after 3 nights and I should have left after 1 night. Worst camp ground I’ve ever been to. I will never return. The ironic thing is this campground was by far more expensive than the others we stayed at in the area. If you stay here DO NOT BOOK SITE 317.

Great site, clean facilites, wonderful staff. My only complaint would be how far we were from the restrooms, but we knew that when we booked (it was all that was available). I would recommend staying here.
