Well you have 2 choices to my knowledge.
Jackson Hole in Jackson Wyoming is the one 95% think of when going to the Tetons so I assumed that was your destination.
There is also Grand Targhee but that is not well known and is not on the Ikon or Epic ski passes.
There is a local non resort called ski King in Jackson I think it has like 2 or 3 lifts only. I wouldn't consider it part of the Tetons but I think technically it is.
I do not know of any other resorts in the Tetons due to fact that they are a National Park and so steep most couldn't ski them if they wanted to. At least that is the 5 peaks everyone thinks of in the photos of the Tetons.
I gave you info on Jackson Hole mountain resort. Again it is not for beginners, very few green runs. I am not familiar with Targhee but I guess look at that one too.
Easy come, Easy go
