Chicago Northwest KOA in Union, IL | RV Park

Went during October.  Lots of activities for the kids.  Camp site decoration competitions each weekend (for Halloween). Trick or treating, hay rides,  etc.  Fire wood delivery to the site.  Bathrooms are clean.  Cabin was nice. Had heat and AC if needed, a mini fridge and electricity.

We stayed here in a 5th wheel, our site had a fire pit, a dog pen and flower box. The park was decorated for Halloween. The park is clean and has a great playground with plenty of things for kids to do. They also have a mini golf course as well. Bathrooms and showers were clean and maintained. We would definitely stay here again.

We recently stayed for one night. The staff are friendly. The location while remote from many things to do around the Chicago area except for the train museum is quiet.

Unfortunately as others have commented the water is brownish and smells of rust. It’s likely iron from rusting pipes that while not necessarily a health risk is not something that’s palatable to most. Definitely didn’t drink it. We fortunately travel with jugs of water just in case we find issues with water at campgrounds. Because of the water we won’t stay again nor recommend it to others.

Stayed in a “Rustic Cabin”. It was nice to have the AC on the humid days we stayed.
Lots of activities for kids.
People staying at other spots were very kind. Staff was helpful and quick.
The only reason for only 4 stars is that the pool definitely could use a few updates, due to peeling spots on the pool walls.
Would definitely come stay again.

Brought my kids here camping for their first time and they had a blast!  The grate to cook on over the fire pit was good enough to cook on after cleaning it, heating it, and oiling it. The bathrooms are clean and are checked on a schedule. The pool looks nice, especially for a campsite, however, it was early in the season so it was cold. The text message system for wood delivery and other items from the store is nice. They had activities for the kids and we all had a nice time! It is gated. The staff is cruising around often and the grounds are clean and well maintained. I will go back for sure! Bravo to the KOA staff for being friendly, helpful, and keeping the place tidy.

Not sure how one rates a campground for rooms! I guess maybe if you did the cabins. We did not. Stopped one night on our way to Wyoming and again on the way back. Bathrooms were clean, the small trailer sites were perfect for our needs. Would definitely stay again if passing through or staying to see the sites.

Friendly staff and well kept property. Location is near Union, IL, which has a cute downtown and a train museum. Price isn't too bad for full hook up pull through. Each spot has a picnic table and fire pit as well. There is also a well stocked shop with fun souvenirs and essentials you may need.

I've stayed here with my family a couple times now and had a great time.  We brought our 21' travel trailer and enjoyed all the activities for the kiddos on the weekend.  The staff is very friendly and attentive.  And being able to text them and have firewood and ice delivered directly to our site is a nice perk!  Definitely recommend and will stay here again.  Family friendly and an easy drive from Chicago!

This is a great campground. The hosts are very friendly and helpful and lots of activities for the kids. We stayed a week while also visiting family in Chicago. It is a bit of a drive to get into Chicago - and we found it easier to drive 50 minutes to the Edgebrook station (Milwaukee NW train to union station) to get downtown rather than driving to Woodstock and taking a 2 hour train.
The entry driveway is a little tight so be careful entering and exiting that there isn’t another rig in the way!

We stayed here in a travel trailer so keep that in mind when you read my review.

Our first impression was a good one when we pulled into the park. As you enter you can see that the campground is well taken care of. We were greeted by an attendant who looked up what site we had and then had another employee escort us to the site. We stayed in a pull through site that was level and the hook up all were in good order other than the sewer hook up was a little far away from us and I did not have a long enough sewer hose to reach it. The campground also has a kid park that was decent, a very nice pool that was very relaxing. The campground also has games you can play, activities on the weekends such as movies and hay rides, and they also have bikes for rent. This is not to mention a fairly well stocked campstore. The showers were clean and free. The bathrooms also were clean and well taken care of. The campground also does have free wifi but it was very slow so don't expect a whole lot from it.

Overall this was a great stay. We had a fun weekend at a nice park.

This campground isn't near Chicago but in the far northwest suburb area.  It is out in the country and convenient to I-90.  We have stayed many, many times in the last 5-6 years and enjoy it.  Very clean, full hook-ups, a pool, playground and a gated area for RVs ($48 per night).  Cabins and separate tenting area available.   Lots of activities for kids on the weekends.  Friendly staff and they do escort you to your site.  Firewood is a bit pricey at $6 a bundle and the wood burns fast.  Nice store, well stocked.  Located right next door to Wild West Town, a nice restaurant and not too far from a railroad museum.  - Review provided by RV Park Recommendations & Reviews Facebook Group
