Liked it better when the tent sites wasn't so close together, it felt like we were packed like sardines!

Had a cabin for six nights. The cabin was great and the attendants were very nice. Will be planning another trip in the next few years

This KOA was an ideal base camp for exploring Yellowstone and Grand Teton National Parks, as well as eastern Idaho. The grounds are well-maintained and offers nice views of the surrounding area. I would definitely stay here again!

The campsites were terrible! There were some traces of rock to set your RV on. The picnic table was splintering and leaning. The weed ground wasn't even trimmed in the 7 days we were there. The worst KOA of any we've stayed at over the years!!! We had much better for $20-40 less a night, with full hookups, on our 3 week trip. Great showers/restrooms and laundry though. Very disappointing.

Nice campground, great bathrooms. Area needs paved as muddy after rain.

was expecting more, our first time at a koa and seemed like a lot of money for 0 amenities and far from entrance to Yellowstone. We paid the same amount at the West Glacier koa and were thoroughly impressed. Did not know there were different levels of koa. West Yellowstone is way to high for what it is, will not go there again.

It was the first KOA on this trip we stopped at that WiFi actually worked. You pay a little extra for KOA you would think the WiFi should be better

The staff was very nice! They bathrooms were great they are individual shower/bathrooms, the staff did a great job keeping them clean and sanitized. Easy drive to get to Yellowstone. Wish there were activities for the kids to do at the campground. There was a small playground but really that was it.

Exactly what I expected for KOA. Clean bathrooms and showers, quiet hours in effect and helpful staff.

Nice wooded campsite. Wonderful bathrooms and laundry. A quick commute to the park.

We took our kids, their spouses and 5 grandkids. It was the trip of a lifetime! It is conveniently located, a gorgeous setting with friendly and helpful staff. Thank you KOA for making this trip so memorable!

Great experience. Despite the current situation with the Pandemic, Very helpful staff. Everything ran smoothly. This KOA is an excellent location for West Yellowstone entry. Family really enjoyed the environment.

I have stayed at various KOS’s as a tent camper numerous times and the bathrooms have always been clean. The bathrooms on my last stay where very dirty. I went once in the evening and again in the morning and the same conditions, both times. Didn’t appear they had been cleaned in a while. Considering the situation with COVID19 the conditions of the bathroom are not just gross they are negligen

I think its a nice clean safe place to stay, I think its a little high in price.

Awesome!!! The folks there were the best. Hope we do that area again we will be staying there again.

This is a very lovely campground and they have a nice store. However, the website says there are tour shuttles. When I asked about them, the manager acted like I was crazy. It is a nice place to stay, but remember, if you do not have another vehicle, there are NO tour shuttles, regardless of what the website says, and they are 7 miles outside of town. Plan accordingly. Otherwise, great place!

The cabin was clean and met our needs. Than you so much.

We stayed in space #1... I personally think it had some of the best sunset views in the camp ground overlooking a wide open field. It is unfortunate that the overflow of flat bed trailers and such scattered the lawn due to it being the edge of the spaces. All the facilities were very clean. It's also just a short drive to the West entrance of Yellowstone

Nice park, spots need to be better maintained grass and full bloom dandelions, perhaps more gravel in spots to make better leveling, but would visit again, spacious spots

We were assigned a tent site near the creek. Perfect setting. Close enough to Yellowstone, less crowds. Bathrooms/showers were nearby. Most everything available at the camp store. Staff was friendly.

Easy and lovely!

The koa was great. Nice facilities with plenty of space and private bathroom area. My only con is that even though it’s close to Yellowstone it was a far drive from the area we spent most of our time. Also, bathrooms had a ton of space but floors needed to be cleaned up more often.

Friendly service, great site, and great location.

Very nice stay! I was impressed by the virus mitigation in the restroom /showers. The mosquitos were vicious but not much you all can do about that. Thanks for all you do!

Lots need paving

We stayed her for 3 nights in a tent. The site we had several dips and bumps, so sleeping on the ground was a little uncomfortable. The grounds are well maintained and cleaned. The staff always friendly and made round regularly. Bring mosquito spray, we were on the side with the main road so traffic was loud but doable. I do wish there was at least a swimming pool for the kids to play in.

Facilities were nice but it was way to pricey. It was the only thing available.
