The setting and location for the CG is perfect. However if it rains that majority of the CG is a pond.

Great location between Yellowstone and Grand Tetons. Staff was very helpful with any issues. Lodge staff was also very nice and helpful and restaurant was good for breakfast (only meal we ate there). Wish there was Wifi in the campground. Campground roads are full of potholes and laundry is very expensive.

A very nice campground, and all of the staff we encountered were very welcoming and friendly. They have lots of trees for shade and only 2 miles from Yellowstone. We will be back!

People were great, very friendly and helpful. Check in was easy. Sites were spacious. Roads were a mess and whatever that was on the ground (not gravel) tracked in awful, especially after the rain. But overall I would recommend. It is very convenient to Yellowstone and Jackson.

As always, the campground was wonderful even has cell phone reception now! We broke down and had to stay an extra 2 days in order to be towed out. They were very gracious in allowing us to stay in our spot. Despite our mechanical difficulties, it was a great place to vacation. We'll be back next year

Make reservations. We had to move twice. This was aggravating but we went on a whim.

We made a mistake in booking our cabin, but the staff was so gracious and took care of things pronto for us. Best staff ever.
