We have stayed here two years in a row, once in a small utility trailer with a roof top tent, and the other in a larger travel trailer. Both times we loved our time and met the most amazing people. Plus the views are out of this world. The hikes are without a doubt some of the best in the country, and the wildlife is beyond anything else we have seen. 

Colter Bay has lots of different loops (some generator allowed, some not, some tent only, some backpacker only). This is definitely a reserve in the future campground. You will definitely roll the dice if you show up here and expect to stay. Some of this may be seasonal, but truthfully the fall is probably just as busy as the summer because of the colors- OH THE COLORS! We have done multiple hikes here and without a doubt the best time to come is during the fall (mid-late September) to see the colors. 

There is a general store at the village as well as laundry, WiFi, propane, and even a restaurant (we haven't eaten here though). Things are, as you would expect, a bit expensive at the store, but if you need it, you need it. The gift store is also a bit expensive, but has some good stuff. There is no cell service in the campground, so the WiFi is nice to have in a pinch. If you really need service or WiFi, drive down the road 10 minutes to Jackson Lake Lodge (or if you just want to see how incredible it is). Spend some time at the lodges' lobby and enjoy the panoramic views of the Tetons. You can order food (sub-par, honestly), or order drinks from the bar. There are multiple stores on the top floor as well.
