The roads in the park are terrible, pot holes, no gravel, water standing 4 days after a rain. So at an average of 500 hundred cabins, tent and rv sites, the price is $80.00x500=$40000 a day 7=280000 a week and can’t afford to spend money on the roads

Lovely campground with warm showers and super clean restrooms. The staff is lovely, and there is free drinking water available near the check-in desk. There is little tree coverage between sites, it's definitely an RV campground more than a tenting area as there is essentially no privacy between lots. But, the services on site (food, gas, stores, etc) make you feel right at home.

Easy pull through, spacious campsite with plenty of shade. The restrooms were mostly clean as were the showers. The limitless hot water was definitely appreciated. The restaurant, gift shop, small grocery and the smaller liquor store inside the grocery were great amenities. Having a gas station, propane fill and laundry on site worked well for me. One disappointment and the only one is the fact that views of The Tetons are not possible from the campground.

This campground is geared towards RVs and camping trailers. Very close proximity to each other. During our two night stay we had rain. The roads and campsites need an overhaul of water drainage management and new gravel. Was a little disappointed with the condition of all of the sites and roads for the cost which is over $100 per night. Staff were very friendly and check in was easy and quick. Propane and laundry is available plus it was nice having a convenient store on site as well.

We spent 3 nights here. Two of the 3 days were rainy and cold. We appreciated the electric hookup and a decent restaurant nearby. Location is excellent for Grand Teton and Yellowstone.

The campground was very full except for the no-shows that reserved spots but didn't use them. We had to move our site after the first night in order to get three nights there. Staff should be monitoring for this especially considering the high occupancy rate they maintain.

It was nice of her to give us a spot, it was late and the campground said it was full. However if I'd known the site was $100 for no hookups and in a mud hole, we probably would've kept going. It actually was our least favorite stay out of a month long journey.
