Colter Bay was a gem to stay in. I stayed in a few different loops during my time there and had a great time at all of them. All of the spots were level and close to bathrooms (super clean and had dishwashing stations which was a huge plus). It was easy to pack up in the morning and head out on hikes early in the morning which was amazing. Some of the sites are close to each other and can be annoying if you have noisy neighbors but overall was a great choice for spending my time in the Tetons.
