We have stayed at Colter Bay Village Campground and RV Park which is a first come first served National Park campground (Dry Camping)
For $20.00 a night, $10.00 for Golden Age or Golden Access Passport, you get a site with a picnic table, fire pit and access to water and flush bathrooms.
Showers are available at the village laundrette with attendents. In the village you can find a general store, museum, marina, restaurant, gift shop and a host other various activites. A short order grill is available that has wonderful food. Be prepared for a wait but well worth it. The chili is wonderful for an evening meal and menu for breakfast is great.
There is an RV Park with full hook ups located there in which reservation will need to be made. $55.00 a night in season and $42.00 a night late season. No fire pits but you do have picnic tables. There is horseback riding and lots of scenic hiking trails and nightly fire-side chats.
We have stayed there at least 5 times and will be back many more times as it is a wonderful place to stay and site see from to Yellowstone, Jackson Hole and points beyond.
If you go to Elk mountain you can see Elk coming down from the mountain to feed around dusk. There is a scenic photo-op from the top of Elk Mountain. Be sure to visit it.
