This was a good location for access to Yellowstone NP. Clean and quiet facility. Friendly staff. Would definitely stay there again.

Wonderful hosts. I had a problem with my hitch and as soon as I told the woman, she had me help within 15 minutes and they went out of their way to get me going again. Great park, easy to navigate. Only suggestion would be to have the site numbers easier to find, as I came in the dark and that was a little difficult. Very clean showers, bathrooms and laundry.

Great location, easy to get our large toy hauler in/out. It's quick to get into the park & the nearby town has good restaurants & shops.

From the moment of our arrival, Kelly & Kathy were so helpful. Kathy got us checked in then proceeded to fill us in about Yellowstone. The park was clean, although the grass at the sites were a bit “wanting”. Having use of a provided bbq was great.

Great place to stay. Wonderful customer service. Bathrooms/showers are the best in any campground I’ve stayed at. The grounds are well taken care of. Loved the escort to our spot.

Very Clean cabins. We have stayed multiple times and really enjoyed them. Staff is so friendly and helpful. A little retreat away from all the hustle and bustle of the park.

Great place to stay and visit Yellowstone. The spot we stayed in was large and level. We had the paw pen which was nice but with the largest and best dog park we have ever seen we didn’t use it. The staff and nice, friendly and very helpful. We would stay here again.

Brittany and Vicky were wonderful; they made us feel welcome and took the time to provide information, blessed us with a free admission to the Grizzly-Wolf Discovery Center that another guest had passed on. Brittany saw our grizzly t-shirts and knew we would be happy to accept the gift. Thanks to the other guest. I wish you had bike rentals for adults, as the email indicated in a picture.

It was nice and quiet, good friendly people. The only drawback is the west entrance to the park is always jammed with traffic.

This is a nice RV resort not a campground. I had a camper wanting to burn a fire in a ring 10’ from my RV. Terrible smoke and real fire hazard with sparks landing on my roof. I hope they didn’t burn my roof. Should be NO fires in an RV park.

It was our 4th stay at Mountainside and we would visit again if we get out west. I love your individual style of bathroom, much more like home. Pizza was great, staff very helpful and pleasant. Sites are large and level, area is quiet and clean. Thank you.

Wonderful to have the dog park. Loved the walk about. Very clean

We liked this KOA - It is very close to the West Gate Entrance to Yellowstone National Park, s only 8 plus/minus miles from our campground. A perfect basecamp . We originally booked for four nights, but we ended up having to change our plans and needed to add an additional night at last minute - no problem able to stay in same campsite - 5th night ended up being more than free due to a deal!

All I needed was a spot near the electrical…with SEVERAL open spots I was told it was full and couldn’t get me a different spot and to go buy a longer extension cord in town.. my first and last koa experience

Nice facility. Very clean and pleasant.

My wife and I wanted to stay an entire week and see Yellowstone National Park. This KOA was great. The grounds are nice, the store was great. The site was in perfect condition. The laundry was very nice. The whole week, everyone at the campground was nice. The staff and the guests. We will be back.

Staff was great! Even did a koa dance and song for us!

We stayed for 3 nights so we could spend 2 full days in Yellowstone touring the upper and lower loops, one day each. The park is convenient to the west entrance of Yellowstone. We had lovely campsites with a view of the mountains and a nearby stream at the back of the property. The campground was well maintained; the staff was competent and friendly. Bathrooms were Buccee's quality!

Everything was clean and in place. Staff was very helpful when we arrived

We enjoyed our stay. It would be nice to have a little more grass around the sites, but the dog park was very nice so not that huge of a deal. The staff were all very friendly and helpful.

A beautiful, well maintained campground, with a friendly staff and amenities that make the stay very comfortable. Being close to the entrance to Yellowstone and a local stop with gas/food is extremely convenient.

Very clean,quiet with beautiful scenery all around. Staff were so nice and friendly. Cabin and bathhouse were in great shape. Easy access to West Yellow Stone and the park. We enjoyed a campfire while sitting on a log.

Expensive with minimum amenities. But proximity to the national park and room for what we were driving/towing won out. I’ve been at nicer KOA’S but staff was friendly and helpful.

Excellent RV PARK! GREAT PEOPLE

It was ok. Really nothing there for the money that charge. Very little amenities for the price.

While we had an issue with a smell in our cabin, KOA personnel tried to remedy the issue. Put in air fresheners which helped the first day. Comping us for 1 additional night was a great gesture.

Friendly staff with useful information to share. Bathrooms and grounds were clean and well maintained. Individual bathrooms were great by providing more privacy. Sites were spacious, with some grass and tall trees (in the back of the campground). Sturdy tables, fire pits and bench swing at every site. Mostly quiet, with just a little traffic noise.
