Very nice facility with friendly and helpful staff. The showers and restrooms were clean and well equipped. I will definitely stay there again.

Mike Jackson, i believe is the manager? He was amazing! He picked our camp spot for us and it was perfect! All the folks there were awesome!

Fantastic Koa. We had a tent site. It was very quiet. Spacious site. Nice bathhouse, very clean, updated and well taken care of. The pizza place was fantastic.

It was my second time staying there. It is great for the cost and easy to get to off the highway.

Planned on only one night, it was so great I stayed for two.They gave me the best site along the forest& stream.

Great location close to West Yellowstone. Clean grounds, nice tent spots by the creek. Very friendly and helpful people. Wi fi was spotty and we couldn't stay connected, but otherwise we really enjoyed our short motorcycle overnight.

Great service. I liked being nestled in the tree line.

Wow. This KOA has the nicest bathroom/shower facilities of any campground I've EVER stayed at. Totally private, not stalls! Plus, I came in 2 mins before the office closed to find I'd booked the wrong night. Office staff got me settled no problem and led me to the site (which is SO helpful when you're coming in after dark). Did I mention my site was creekside?! Quiet, beautiful, great stargazing.

It was a great camp ground but a pool would be nice as well.

We loved the people who ran the KOA, definitely nicer then some of the other people at other KOAs. The pizza they sale is delicious. The mining is fun for the kids but over priced. There’s literally nothing there to do other then the mining and playground for people who stay with kids. No shade at the tent sites which sucked because we had to find other things to do during the day instead.

As always a wondereful place.

Tons of mosquitoes! Otherwise nice. Great workers, nice camp store.

Nice facility but not happy with my tent site. No grass to set my tent on and with the rain, I had a muddy area. Also, being close to stream I had to deal with mosquitos

Loved the location of our tent along Denny’s Creek, but not the misquitoes!

We didn't realized it was going to be cold this time of the year. We were fearful of bearing warning and we were unable to rest well.

We had a tent site next to the creek, which was nice. The laundry/shower/bathrooms are very nice!

Two things really irked me during my stay... They sold the lot next to us to an RV which really crammed us into already tight tent spaces which was pretty sad. The other thing that bothered me quite a bit was a big bright ‘street light’ that they said that they had no way to turn off even after inquiring. So if you’re looking for a even partially secluded stay... this isn’t it. Nice staff

Our stay was amazing and we can't wait to return. The only thing I would say is maybe a little more upkeep on the bathroom/shower area. This was our first time to the area and it was fantastic, friendly staff, clean camp area and very beautiful Thank you so much.

I liked it a lot...the tent sites could be a little more level but all and all a great campground...exceptionally clean bathroom and shower

Great location, tent sites were next to a cute, babbling brook. I would definitely stay again. Facilities were very nice.

Loved our spot by the creek. Liked how the showers and toilets were in private rooms. I only give it 4 stars due to the bathrooms were fine, but needed more constant cleaning. Very busy week when we were there so more attention to the bathrooms was needed. There was hair in the showers and slick dirty floors and soap left empty by sinks. Nice playground, office and store. Overall great time.

Very basic campground. Few amenities. The store is well stocked though, and the staff is super friendly.

Tent campsite was nice with a stream just feet away from the campsite. The bathrooms / showers / laundry were very nice and kept clean.
Jul 28, 2019
We loved our tent site that backed up to the creek and pond. The staff was friendly, the bath house and facilities were clean and maintained! Great jumping off point to roam Yellowstone all day!
Jul 28, 2019
Great spot and ideal location near the entry to Yellowstone. Nice showers and toilets.
Jul 27, 2019
Improve your WiFi for your overpriced tent sites. Otherwise my stay was great!!
Jul 25, 2019
The staff were very friendly and the gift shop had some nice and reasonably priced souvenirs. The downsides were: very few sites with shade (none in ours or the neighboring tent sites), further away from Yellowstone than expected, bathrooms and showers were always dirty (garbage full, hair/soap in shower, floor wet) no matter what time of day.
Jul 25, 2019
I wish I could give more stars! Super accommodating, friendly and joking.
Jul 24, 2019
Wonderful. The manager is too notch. Saw to our every need and really made us feel welcome. Thank you so much!
Jul 23, 2019
Great stay! Great bathrooms, great view, helpful staff
Jul 22, 2019
My only complaint is the lack of bathrooms/ literally end up waiting for a minimum of 30 min to get in and people are rude and start banging on the doors! Other KOAs we have been to are set up or women bathrooms with several toilets and showers making it so their is no wait. Other than this issue the campsite was quiet and the staff was very nice.
Jul 21, 2019
Great campground. We pitched our tent on the stream. The only issue was some bizzare weather and wind that came through. Wish you had more showers. Otherwise, a perfect place to stay right outside the gate at Yellowstone.

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!
