Campground Reviews

The staff was really nice! The deluxe cabin had everything we needed to make our stay comfortable! Our kids played on the playground each night, we had a lovely campfire with the view of the mountains in the background, and we even had a pizza from the store the last night which was delicious. It was a great campground base in West Yellowstone to explore the park!

RV sites seemed nice but we were tent camping. No fire pit, no bear box, very clear that RV is preferred guest. Whole site was clean though and staff were FANTASTIC! Loved the dog park and shower facilities.

Great sites, great location, great staff and store

I will never look for a spot in a KOA again. To no fault of the friendly and helpful staff. The exorbitant price is not justified by the private bath and shower in the unisex bath house. We really enjoyed the $50 pizza, bring our night's expenditure to $200 for a standard pull-through site, whose sewer hookup was too high for easy use. Noisy and busy up to and beyond the 10pm quiet time. Never aga

We stayed here to visit Yellowstone which is a short drive away. Great place, nice camp store, especially the pizza and draft beer, fantastic employees, all in a nice quiet environment. We had zero problems. It would be nice to provide some seating in the laundry so you can sit and read while your laundry is washing or drying, instead of having to walk back to your RV.

The staff are great! Very nice and extremely helpful. The best review I can give is we come back every year!

Great stay in a clean cabin.
Jul 21, 2025
The grounds were well kept, the bathrooms were very clean, and the staff were friendly and helpful. We had a large grassy site that was big enough for our large tent. The campground was quiet around 10pm and other guest were courteous. Hope to come back next summer!

We had a great time, the campsite is very pretty and close to the West Yellowstone entrance. We used the laundry and shower facilities and they were clean and well kept. Staff is friendly.

Nice camp ground, cabin was perfect for our trip and staff was very friendly. Would stay there again.

Great little park. Friendly staff. Laundry building was so clean!

Great Park, Manager And Staff Were Great, Great Stop For A Night Or 2, Highway Noise And Train But Easy On And Off, We Will Definitely Stop Here Next Time Up This Way

This is my 2nd time tent camping in the same KOA location. My neighbors were great and respectful. The staff was great and helpful. If anything, the only struggle was how small and lack of parking for my SUV in my 229 tent camping spot. But I made it work!

Someone took my clothes out of the washer and mixed it with their clothes in the dryer. No ones fault. Things happen. I reported it to the staff because at that point I hadn't figured out yet where my clothes were. The staff was very good in trying to help, however, when the staff mentioned this to the manager who was eating, he was very dismissive and could care less. Didn't even acknowledge me.

We enjoyed our 5 night stay! Perfect location for day trips to visit Yellowstone. Highly recommend Mountainside KOA. Very clean facilities and beautiful area. The pizza was delicious from the Mountainside KOA Cafe, too.

Wish it had a pool

A great place to base camp for Yellowstone. We loved it! It’s a little drive into west Yellowstone but it’s worth but a little further away for some peace and quiet! Great spots with swing chairs and fire pits. Beautiful stars and sky. Great for the kids and their newer cabins provide the perfect space for a family of 5. Definitely recommend and stay an extra night or two so you can enjoy the

We enjoyed the campground and the deluxe cabin exceeded our expectations.

We stay in a lot of KOAs and the patio sites here were small for the price. The extra charge to lock your site was crazy, I always lock my site but at 20.00-25.00, not 50. We paid 40.00 for 3 bags of ice and 2 bundles of wood - ridiculous. I feel you are price gouging at this location because you can where it is. Not really happy with this one.

Location ia great with only a short drive to Yellowstone (<15 min). Washers were out for a while but fixed later in the afternoon. Staff was great and responsive. Maybe more bathroom cleaning throughout the day give the usage at peak periods. We would stay again.

Bathrooms need to remodeled and cleaned more often. Staff is very professional and friendly

Thus is a very beautiful and we'll maintained park, and the office staff are absolutely �� amazing!!! The facilities are user friendly and available and the park grounds are enjoyable as well, the only downside is the "overpriced feel" of literally everything. But, they have an absolutely awesome RV repairman named Joseph if you're in need. He is truly trustworthy and pricing is very fair!

Staff was friendly, kind, and helpful! Site was well maintained.

Everyone was very friendly and helpful during check in. My only complaint was that it was very dusty. The new dog park is amazing and our girls loved being able to run around in such a big area.
Jul 16, 2025
We have stayed at several KOAs and this so far is our favorite!! Beautiful scenery, nice places to walk the dogs, easy drive to Yellowstone. We definitely recommend this KOA.

The campground was clean and generally well-maintained, which we appreciated. However, there was very little shade throughout the area, making it tough to stay cool during warmer parts of the day. We also ran into some trouble with the washing machines—they weren’t functioning properly and added a bit of hassle to our stay. Overall, the experience had its ups and downs.

This is a great place to stay while visiting Yellowstone National Park. The staff is very friendly and helpful. The CG is well maintained. Our site was fairly level. Not much shade. Would definitely recommend.
Jul 16, 2025
Great people and excellent service. Site was very tight and unable to open all slides. Although DOG PARK was brand new and beautiful it was FAR TOO large. I would suggest dividing into 2 or 3 parks. Small dog/ large dog style. Not all dogs get along and this would make tending to dogs less stressful.

Nice quiet site near a babbling brook.

Great location. Tons of amenities. Helpful and friendly staff. Lots of options for sites.

4 nights, tent site: Cleanest bathrooms ever! Great location - only minutes from the West Entrance to YNP. Can't wait to visit again.
Jul 14, 2025
Cabin 312 was great for 3 people. The hot water was scarce. Plenty of towels and linens were available. It was nice to have bath soap and shampoo in dispensers. Could use a kitchen scrub brush. Thanks!

We love staying at Mountainside. It is so peaceful. Everything is clean and tidy and ithe staff are great. Our pup enjoyed the new dog run a lot.

The campground was fine. It was close to West Yellowstone. The bathrooms smelled, and the showers were not always clean. The store was greatly overpriced ($12.50 for wood and $5 for a small bag of ice.) There wasn’t a pool or any extra amenities or activities that many other campgrounds offer.
Jul 13, 2025
Overall the park is clean and well maintained. A few issues that we saw are as follows: in our site as well as several others the sewer inlet was too high so I was unable to able to drain my tanks. Both corn hole games were falling apart and should be repaired. The dog park was great as was showers and bathroom. The park needs a pool to compete with other campgrounds in the area

Wonderful site with wonderful staff willing to help and friendly. Just 15 minutes from Yellowstone entrance with a beautiful campsite.

Third time staying here. Great views. Quiet sites on the creek. Friendly staff.
Jul 12, 2025
This is a lovely peaceful campground. My only issue is that the toilets in the laundry room were not clean. Also I’m glad that I washed down the laundry folding table because it took several sanitizer wipes to get it clean.

Prima verblijf, wij waren op de fiets en dan is het jammer dat de afstand en drukte op de weg naar West Yellowstone zo groot is. De camping zelf is prima.

Nice, friendly but was discouraged. The store staff suggested to not be outside in the evening because a grizzly and black bear were in the campground the prior week. Unable to enjoy campfires.

was a nice place to stay close to yellowstone park west entrance, but out of town. nice restrooms and showers.

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.
