Campground Reviews

Sep 19, 2020
It was a quiet campground. Didn’t hear a lot of traffic. Very close to West entrance of Yellowstone. Bathrooms and showers were nice but they didn’t keep them as clean as I’d like. The campground was full and I understand there’s lots of people in and out.

We had a great time. You are not packed in tightly it the sites like some Rv parks. Staff was friendly. We made reservations already for next year!

We were traveling with a group of friends / 3 rvs And one of our group was given a spot farther from the 2. When we requested it at check in the counter person just laughed it off . Did not give any explanation and just ignored us . After pulling in we notice there was available spot closer to our 2 friends. Our spot was tight next to a tree with class A. Need better customer service .

We came in late and were giving a site near the restrooms. No problem as we warned it was near the restrooms and electrical box. What wasn't mentioned was the LP tank 10 feet from where we were supposed to have a fire. Not ok especially since they charged us $89 - you are taking advantage of customers. Will not recommend or stay at ANY KOA's again. Seriously, shame on you!

Campsite and bathrooms were clean. Campers were respectful. Only down side was the road noise from the highway

Shower hot water was broken, and when we checked in, they said it would not be fixed during our stay.

Pasture like site very uneven terrain, had to lift one side of the camper 4 inches to reach level, but there was water coming from a leak under that tire, when we left we had settled 2 inches, picnic table was horrible, couldn't use it, when you tried to use it it would totter. Asked to be moved, told nothing else was available, sites were booked 10 months ago. Horrible experience, don't know how

Staff was excellent and every single one of them had a great attitude. Also, the facilities were always clean, and the store was nicely stocked. This was definitely a great camp trip!

Bathrooms were filthy anytime we used them.Wonder if you could hire someone to clean them every half hour since your business is doing so good.

Site 65, worst site/campground we have ever had at koa. Shame on koa for charging $80 per nite. Sites are Uneven grade,sewer hookup were useless,wifi useless, sites are stacked too close together,no shade,couldn't wait to leave. Regrade the sites, adjust the sewer drains to ground level,put in wifi boosters

Staff was responsive and helpful. They remained professional at all times (even when some guests were being less than kind).

Had a great stopover

The park was full but I was assigned a site next to the tent area which was fine. I was in site C166 and it could use some leveling. Everything was fine and I had a comfortable night. The price was good too, comparable to other KOA RV parks.

We come and stay there at Mountainside every year. We paid $20 more a night for our stay this year over last year and we were pretty disappointed with site #23. Our picnic table was unusable because of how chipped the stain was and the site was so uneven that you literally had to be super careful of where you stepped. We also were never warned about removing hoses due to freezing temps. Shocked!:(

Everything worked as it should. Nothing special, but a perfectly fine place to stay for a few days.

Had a great time, all staff were friendly and very helpful. Sites are large and spaced well and very clean. Budget rental was very accommodating and gave us a car to drive around in.

Cabin was great! We loved the fire pit and patio. Location was excellent!!

People were very friendly and they had a nice area to walk the dogs

We had a great tent site along the stream which was a great location! Loved the ease of access to the West Yellowstone entrance from the campground - just a quick 10 - 15 minute drive. Having showers available was a nice convenience. Only downside is that our tent site (and others I saw) didn't have a typical fire pit/ring - just a grill to put over a fire of your own making.

Check-in and out were so easy and convenient because we were arriving so late and leaving so early. It was easy to find our campsite and the facilities were plentiful and clean.
Sep 14, 2020
The management was great. They were able to find me a spot last minute on a busy weekend.
Sep 14, 2020
I stayed in cabin and it was great!!! Will do again

Conveniently located to access West Yellowstone. Just a few minutes drive to the entrance. Cool, complex creek and forest land directly behind for easy exploring. Those tent camping can have a spot on the creek. Nice, clean showers and restrooms. Fairly good pizza and friendly staff. Downside was some road noise from trucks and our site was on a bit of a tilt.

Great site in the back next to a pine tree. Very clean laundry and showers. Loved the store and pizza!

Lovely cabin spot next to a creek. Surrounded by evergreen trees. Wonderful location for our yellowstone base camp.

The site we had was large and well maintained. The laundry room was the cleanest I have seen in a while. A suggestion would be to only allow propane fire pits. Smoldering fires are not environmentally friendly nor to other campers. We couldn’t open our windows due to wood fires. We had to run our ac. That adds more to the KOAs electric bill and lowers our experience of wanting fresh air.

There were many open spaces and we drove 11.5 hours to meet up with friends from Colorado we haven't seen in years. They are KOA members. We know you can't reserve spaces but when we got there, we told them we would like to be as close to our friends as possible. We were at opposite ends of camp. All the days we stayed there, those spaces near our friends were never filled. Didn't make any sense.

Staff was great, sites are a bit tight for a 40’ class A RV. The biggest issue was the clean out pipe was nearly level or higher than my RV waste pipe so impossible to fully dump and clear the hose. Need to raise the gravel site number 4. Otherwise great views and friendly staff.
