Really nice campground. The site was clean and the restrooms were well maintained. The convenience store and restaurant were excellent. We found a great hike out to the hot springs and were able to walk a short distance to fish at the Snake River. Great location.

*** Der Sammelpunkt für leere Gaskartuschen ist großartig! ***
Cabin und Camp sauber und gepflegt.
Die Waschräume ebenso.
Mit der Tankstelle, Laden und Gasthaus gleich nebenan ist alles für die Versorgung vorhanden.
Der Beste der von uns im Urlaub besuchten Campgrounds reserviert über recreation.gov!
Danke

what a wonderful experience we had. Lovely Park, showers, and sites. Compliments go to Mary from Mississippi, the registration agent. She was one of the nicest people we've met in a long time. She was able to find us a third night due to a cancellation. Overall, a great, great experience.

Many campground sites and access roads need grading to remove potholes which were filled with water after recent rains. Overpriced! Poor value.

Campground was nice but this employee not related to the campground was always hanging around when I tried to go to the office a few different times to get information. He obvious worked somewhere there because he had a different colored uniform but I could never get to ask what I wanted due to his interference.
He had attitude I did not appreciate either. I felt bothersome at this point.

Campground is conveniently located between Grand Teton and Yellowstone. Hot showers were nice after backpacking. We heard wolves in the morning. Sites are close together. We ate breakfast in the lodge: Food was excellent; service was quite slow.
