everyone was extremely friendly and quite convenient to both Yellowstone Park and the sceneic byways that I wanted to see.

The weather was cold and rainy, but we had a great time anyway. The Pizza in the Lodge was wonderful. The showers were the nicest we have ever seen in a campground. The laundry facilities were also clean and neat. The park is about 7 miles from the West Park Entrance in Yellowstone. I recommend this campground if you are visiting the parks.

Very nice campground

We had a tent site with bathrooms and shower building only 100 feet away. The camp had individual unisex bathrooms (sink and toilet) and showers in the building. Facilities were clean and well arranged.

We had reservations in the park for five days and stayed here the day before we stayed in park. It is a perfect place to stay either short or longer term. We camped here and enjoyed the park on the same day. The facilities are great with good, private and warm showers and restrooms.

Mike and Donna are fabulous! Kind, helpful and friendly! We are traveling across country! We are a month in. This was our best camping experience! Thank you Mike and Donna for being so kind in our dilemma!

My husband & I feel "at home" here because of two basic yet important feelings....Safe, and, Sound. The people that operate it's success, radiate in their own individuality with kinship...reflecting the true treasures this special place holds. We hope to return, God willing, to take in once again, it's magnificent offerings of "blessings bold"..... all around! Tory & Wally

Can’t say enough good things about this park. The entire staff are very friendly & helpful. They were very knowledgeable about the area & things to do. The bathrooms, showers and laundry were impeccably clean. Large sites and the view from the campground is amazing.

Great

We checked in late but they were very accommodating. The site was great. WiFi was pretty spotty. It was a great location, close to the park, but not in all the congestion.

Enjoyed it very much...Very nice people ..and very nice park..!!!!

Dog park is to small. Need to make it longer. About 20-30 feet so a dog can chase a ball.

All staff members were very friendly and helpful. It was a great first experience with KOA. We will definitely stay with KOA in the future!

The camp was clean and well maintained. The bathroom, shower facilities were warm and clean and never ran out of hot water. There was a nice walking area and two casting ponds as well. The only downside for us was noise from the adjacent highway, which was probably worse for us because we were in a tent trailer. I doubt it would be noticeable in a hard side camper. We will likely use again.

Perfect in every way possible

Very nice KOA. Management was very helpful and knowledgeable.

Very nice location and only a few minutes from entrance to Yellowstone National Park. We enjoyed being in the mountains and near such a nice creek. Our dog enjoyed his walks by the creek and into the National Forest which borders the RV park.

Efficient and friendly check in. Great showers. Wonderful views. Wide sites. Just a nice place close to west entrance to Yellowstone.

We enjoyed our stay very much, excellent staff.

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.
Sep 26, 2019
Very friendly and helpful staff. Large sites and a short drive to West Yellowstone. Will definitely go back again.

Beautiful park well cared for by very friendly staff.... eventhough it was late in the season it was perfect.

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!

Very welcoming and gave us great information.

Awesome !

Nice clean site and easy excess to ATV trials.

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.

Great facilities....super clean and well maintained. Nice level sites. Very friendly and helpful people.

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.
Sep 20, 2019
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.
Sep 20, 2019
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 go to Yellowstone every September and we have stayed here for the past three years. It's always clean, the staff is very friendly and the office/giftshop has a good variety of stuff. The man at the office even lent us a tool we needed, that kind of hospitality is the main reason we stay here. They also have a nice play area for kids and a nice fenced off dog area. This KOA is beautiful year round!
