Great restrooms and laundry facilities. Cable TV was not good,bad picture, unwatchable, so we stopped using it. Local over the air stations were much better. Internet service was adequate but not good with lots of users.

Very friendly and helpful staff. Large sites and a short drive to West Yellowstone. Will definitely go back again.

6 days in Yellowstone with our family together. This rv park is beautiful and just a few miles from the entrance to the park

This park was ideal for our visit to Yellowstone National Park. It had excellent wi-fi and a good variety of cable stations, but you must ask for the delux site in order to get cable. The site was long and easy to maneuver through. There was a children's playground. The staff was friendly.

This is a nice, roomy campground. It also has a bonus: a pizza restaurant adjoining the office!

We had a nice spot with a great view. The Calzone and Stromboli were very yummy and bonus to not have to cook! The warning of a close brown bear added a little spice to the evenings... the only down side were the mosquitos, they were terrible!

The facility was top notch, our site was really nice, neatly designed, nice grass. The camp store was nice as well. We didn't use the restaurant as it was closed for the season. My only critique is that the waste pipe was a bit high so you know the saying, it doesn't flow up stream. That was a bit of a challenge.

Pros; great location, laundry facilities on site, hot showers, and area for kids and adults to play. Cons: in the morning WiFi didn’t work at all; not even slowly. Prior to booking the site we asked what time they clean the showers and were told “we start at 10”. Around 1pm we went for showers. The facility was emptying and it was pretty dirty/muddy due to rain.

Relaxing, refreshing, just the way vacations should be. Beautiful all around. Was really glad for the laundry/showers. Thank you for providing a great atmosphere! I will recommend your location to all our friends and family.

Very helpful and friendly staff.

Good location, a little road noise and the site could use a little TLC, dips and holes that could twist an ankle and it wasn’t real level.

The Good: Nice clean park, nice folks who run it. Nice playground, nice dog park. Store inside office. The Bad: Sites very close to each other. The Ugly: Sewer hookup is uphill from your rig due to site slope. Makes it a little hard to dump the tank.

Fantastic campground close to Yellowstone. Staff was wonderful. Sites were wide and clean. Bathrooms immaculate. And the views were to die for. This has been my favorite KOA of all the ones we have stayed at. Looking forward to a return visit some day.

We had a reservation for a specific type of site. We arrived @ 6:30pm and everything was full. We were put in a site that was nothing but water and mud as it was raining. Our RV was sinking in the ground by morning. Very disappointed that the type of site we reserved was not what we were put in.

This location was a nice place to stay. The facilities, showers, laundry were clean and well maintained. The only downside was the sites where we were were not level. The staff was polite and friendly. Overall a good experience, a great location from YNP. Thanks

Knowledgeable and friendly staff. Close to West Yellowstone and entry to the park.

The site I had was not level at all. I had to block the wheels and use the jacks to make it right. They had plenty of equipment and piles of stone to make it right but thye had no concern to do it. A comment from a girl in the store when we asked for something was "We don't have any more and it's getting late in the season so we won't order any more"! Well I should not have had to pay full price!

Nice reception with everything you need. Quiet and clean. Strongly recommended.

Great staff!! Very helpful. Easy to checkin. The site needs a little more shrubbery.

Good store and friendly, efficient staff. The bathrooms and showers were among the cleanest & best I've seen at KOAs. However, the pull-through, full hook-up sites were mediocre at best and the WiFi was absolutely awful. They definitely need to improve their WiFi, after all, this is 2019--not 1999.

Warm eye contact on arrival, efficient and thorough check-in, clean and user friendly bathrooms! Thank you!!!

Beautiful area, nice campground- fairly clean facilities. Definitely not doing everything they can during covid.

We found this KOA to be well kept, organized, and clean. The spots are fine. The staff was helpful, except that they were not often wearing masks inside the office during the COVID-19 crisis. We found this to be a disappointing lack of concern for guests.
