Best RV Parks & Resorts near Mills, WY

We actually would rate this KOA campground as 3.5 stars, because there are some redeeming qualities, but overall it is a better place to just pass through for a night than to plan a long-term stay.

The location is very nice, being just north of Casper, Wyoming, and easy to get off and on the interstate. Surprisingly, this campground was rather quiet despite being near the highway. In addition, there are two bar and grill style restaurants that you can walk to within a couple minutes.

This campground has level sites, but everything is gravel outside of the playground. There are two areas that offer shade trees, mostly for the big rigs, but most sites are out in the sun and close together. We had to share our water and sewer area with the camper next to us. Luckily, he had an adapter for the intake hose, because his outlet was stripped and he could not hook up otherwise. I did not see any tent campers at the time of our stay, but there is a small area available that was grassy.

The pros of this campground include an INDOOR pool, which was heated and felt great. They have a mini-golf area that is due for renovation later this summer, so it is currently offered at no charge. It was fun enough for our 10- and 6-year-olds. The playground is small but nice, and the bathrooms are well-kept. We did not use the showers.

Another pro was the host, Susan. She was very knowledgeable about the area, sociable, and willing to work with anyone who had issues. I found her fun to talk with and she even gave our kiddos some free KOA cups!

Overall, if you need a place to stop for the night, this will suffice. If you want to park comfortably for a couple of days or more, you may want to look elsewhere.

I liked the little dog park and river access.

I mostly didn’t like everything else… from what I’ve been gathering, they put their long-term stays in worse sites which seems strange? RV sites are extremely small. Whoever was in charge of the website's marketing did a bang-up job, because let me tell you, the reality is a far cry from those picture-perfect images.

This campground, is nothing more than a flat, uninspiring patch of land that will transform into a mud pit at the first sight of rain. Shade? Forget about it. You'd be luckier finding a needle in a haystack than a sliver of shade here. And good luck tracking down any staff – it's like they've perfected the art of hide and seek. The office "closed" sign is practically a permanent fixture. So, if you're in the middle of a long-term stay and something goes awry– you're pretty much on your own.

What I LIKED: The little dog park and there's also river access, adding a touch of nature's charm to the experience.

The campground(CG) was easy to find and check-in was a breeze. We were originally in site 53 right across from the office but that would have been way too small so we were moved to site 43 which is a long FHUs pull-through. The manager spent time chatting with us about the CG and interesting happenings this last season. The utilities were smartly placed in the middle of the site. WiFi was above average. There were a few seasonal residents who were working in the area. We got a solid variety of OTA channels and were able to get our satellite to connect. The trees in the CG are young so provide some shade. Our site didn’t have cable but some do. There are also premium sites down by the North Platte river that runs adjacent to the CG. There are also tent sites by the river. There is a fiber optic cable facility near the CG that runs 24/7 to include weekends, so there is some noise during the night i.e. backup beeping from forklifts. However, our air conditioner and/or sound machine easily drowned out the noise. As this CG is right outside Casper, there are a ton of amenities nearby. There are nice areas to walk our pups by the river. We enjoyed our two nights stay to include doing some fly fishing in the river at the CG and would definitely come back.
