Stayed in a camper cabin. It's the perfect inbetween if tent camping and hotel stay. You can reserve a site online. There is a bunk bed with a thin cushion, a table with 2 chairs, and 3 drawer dresser. That's it.
Bathrooms are a 5 min walk. They have flush toilets, hot showers, several sinks inside, one sink outside for dishes. It was late September so it wasn't busy. The showers are private. You walk in, close the door, undress, walk into the shower and close the curtain. It is as private as any public restroom stall. I am a woman who was on her period. There were trash cans in each bathroom stall for sanitary napkins and tampons.
Headwaters is near the south entrance of Yellowstone. We were able to visit both Tetons and Yellowstone with ease. Lamar Valley is 2.5 hrs and Old Faithful is 1.5 hrs.
We saw the most animals in The Tetons.
There is a restaurant, coffe shop, convienice store and gas station at Headwaters lodge. 100% reccomend.
