My family and I enjoyed this campground a lot. It’s almost impossible to overstate the convenience of its location. It’s near both Yellowstone and the Grand Tetons. It has a confidence store, restart, and gas next to it. Additionally, it has all the typical camp ground stuff one could ask for. It greatly improved the efficiency of our time int the parks and allowed us to enjoy relaxing together each evening.

Nice campground. Roads needed to be graded. Would be nice if roads and spaces were paved as in many other parks.

I was lucky to get a cabin for the night since I arrived without a reservation in the early evening. The cabin had a bed , a table and three drawer dresser. The bathroom required a 3-5 minute walk which was the one thing that was really negative about the campsite. There was no electricity in the cabin. Build more bathrooms!!!

The site was average, and the location was excellent. However, we were impacted by the dust in the campground.

The attendance were very friendly and help full. Our 2 kids stayed in a cabin in the RV park and it had just a bunk bed and desk. My wife and I stayed in our Camper Van parked out the cabin. The Cabin was nice and clean but a little pricey for no water or electricity.

We enjoyed our stay! Very convenient location. Sites were a little tight. WiFi only really worked well if you were near the laundry room. Overall, nice place. We’d go back!

The bar menu was the FIRST food, made by someone else, that we ate in at least 10 days. Ed was ALLL ALONE (attn; management) but very accommodating and the food/drinks were SOO TASTY. He had a full room of people to wait on, by the time we left. We were so grateful to have real "bar food" and it was way better than that description. We returned the next day for dinnner in the dining room area. 5*

The campground was well maintained. They have sites able to accommodate both our RVs including our daughter and son-in-law's 43' 5th Wheel. The sites were good sized and not crowded. The staff was friendly and very helpful, giving us pointers on where to see wildlife. The lodge is close by and has a restaurant, gift shop, small grocery store, and bar. There is a gas station on site as well. One thing I especially appreciated were the multiple reminders that our visit was upcoming. We had several sites booked at several different parks, so getting a reminder for each site was helpful in keeping track that we had reservations for everyone where we needed them.

Overall nice place to stay. Wooded and close proximity to YS South Gate and. Grand Teton’s. Only negative is that it is very dusty and the mosquitoes were unbearable. Everything at the campsite worked as it should.

The campground was nice. The showers needed a little upgrade, but it had everything you needed. Pretty location with the river just a short walk away!
