Me and a buddy drove 20hrs to come here and we were not disappointed. The views are beautiful and we were lucky enough to see a bear during our stay. Only regret is not booking a longer stay.

Facilities exist, but need improvements. Wifi is not available in most sites, and are not reliable except in the store, 100+ yards away.
Sites are difficult to find and locate, even after staying a day or two. Stuff are new and need better training before starting their jobs. However, it is the only campground in the Teton area, and is not cheap.

Would stay here again. In the Tetons and 2 miles away. Little cabins are perfect and they protect you better from the elements when the weather changes. Nice to have a gas station by though prices are 50 cents higher than Jackson Hole but a lot easier if you need to fill up than driving 55 miles back. Staff is so friendly and helpful. If you need a good meal the lodge has a good burger which we did on our 1st and last night. We did breakfast one morning too and the breakfast burrito was huge and comes with home fries and we also ordered biscuits and gravy which was so delicious. Everything was great about this stay.

I had called in advance to be sure that the cabin had sheet, pillows and blankets. I was misinformed though. It was cold that night and J was very cold.
The restaurant was lovely. I ate dinner there and breakfast the next mornjng. Both meals were good.

I was lucky enough to get the last tent spot available on a whim. Great facilities.
Only feed back is to have a small shelf and LOADS MORE hooks in the shower stalls.

We had a great time. The cabin was great. We had some cold nights but the cabin was so well insulated we kept warm all night. The double bunk bed was perfect for our family of 4 (2 adults, a toddler and a baby). We just put the top bunk mattress on the floor Bathroom's were always clean. But no hot water at the sinks. Shower Also seemed cold
