Best Campgrounds near Mills, WY

I stayed here in late September and it was pretty busy, most or all of the sites were taken. I stayed in site 1, which I think is the most level. I was able to get perfectly level without any blocks. The pit toilets are on the other side of the campground from site 1, it's about a two minute walk. They were clean and usable. There is a dumpster by the bathrooms.

It's very dry here, not much green. There are a lot of flies and other bugs but none of them bit me. The river is beautiful but it is a ways down from the campsites. It's kind of a rough path to get down close to it. Several fisherman were doing it though.

I don't think there are any rules about generators, I noticed one camper seemed to be running theirs almost 24 hours a day.

The picnic tables and fire rings are in great shape. Each picnic table has a shade shelter over it.

I had great speeds from AT&T and Verizon here. My T-mobile device roamed onto AT&T and had a great signal but was slow.

There is another campground closer to the main road called Gray Reef Reservoir, I checked that one out too and it is very similar. But I prefer this one (Pete's Draw), mainly due to the site layout.

This is a great campground for an overnight, but you probably wouldn't stay longer unless you love to fish.

The campground is large and open. It's arranged so that there are limited wet/energized spots, with the rest of the ground catering to tents and dry camping. In the center of the property, there is a "community" kitchen. There's also a laundry room with a heated shower for campers to use. The site has hammocks, horseshoes, Cornhole and plenty of space to fish and relax. 

Would definitely recommend to friends and family.

In a word , the animal interactions were great as you walked among them. Dewayne was supper friendly and definitely from the cloth of a rancher we did not get to meet his wife.

Looking back at the photos I have from that morning, I still believe we couldn't have found a better place to stay to start our journey!

We were not able to make our reservation due to a flat tire 30 miles from the destination.  Left a message around 5 pm that we would be late.  Then provided an update around 8 pm when we found out roadside assistance would not be available until the next morning.  Without requesting, I was told my fee for the night would be refunded.  Thought that was good customer service.  i was not expecting a refund.

We arrived on July 4 for an overnight stay.  Great staff, we were taken to our site by a staff member and assured that if thee was anything we didn't like, we could change.  It was quiet, even for a holiday, and the fireworks were a couple miles away, so we could see them but not hear them.  A plus for our super anxious pup who doesn't like thunder or fireworks!

Nice little campground. Some water spigots around, a couple dumpsters, a vault bathroom. It’s fairly close to I-25, but wasn’t bad from 9:30-6:00.

Amazing hosts. The animals were so fun to get to know and we loved touring the farm with the hosts. We arrived very late at night and they came out to greet us. I thought we would have electric hook up as part of the site, but that’s not available. I mentioned that to the host and in the morning they had run an electric cord out to our trailer, which we didn’t end up needing. The views are also spectacular of the Casper landscape. I highly recommend this as a unique camping experience!

Waking up among alpacas, lamas, donkeys and an incredible horse with an amazing sunrise (and probably sunset but we missed that).

Owners made time to show us around the animals in the morning and gave us some much needed coffee.

Highly recommended

Deer Haven is a rustic haven for campers, boasting 11 reservable campsites and a single restroom. It's worth noting that water and utilities aren't accessible at this campground.

The campsites are delightfully primitive, aligning with a check-in time of 3:00 pm and a check-out time of 11:00 am. During the hours of 10:00 pm to 7:00 am, a peaceful atmosphere is maintained for a restful night's sleep. 

What makes Deer Haven stand out for me, personally, is its remarkable seclusion. They’re sites that are nestled away from the main road, it's enveloped in a serene setting with ample tree coverage. This campground has earned its place as my favorite in the area, offering a tranquil escape from the everyday hustle and bustle.

The office building has convenient amenities, boasting well-maintained men's and women's bathroom/shower rooms, as well as a set of 4 washers and 4 dryers- all of which made my stay even more comfortable. The camper hook ups were a breeze, with flawless water, electric, and sewage connections. 

I especially appreciated the concrete slab next to my camper, perfect for grilling, playing bag toss, or simply relaxing in chairs. The location couldn't have been better- nestled right by the city park, I felt the location was perfect. 

Being close to Deer Creek added a touch of nature to the experience. I noticed ongoing improvements, such as the replacement of gravel sites and the addition of new cement slabs, truly showing a commitment to enhancing the RV park. The presence of shade trees was nice, and the adjacent city park, complete with a dog park, was a fantastic bonus.

The showers were both clean and pleasantly warm. The overall decor felt a bit outdated but still satisfactory. While there was some noticeable road noise, it didn't reach unbearable levels. The lodging area is situated on a gravel lot, lacking picturesque views. However, if you're seeking a one-night stopover, it serves its purpose well. Furthermore, considering its affiliation with KOA, the pricing remains budget-friendly.

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.
