KOA's closest campground to Chicago, about an hour out of the city in Union, Illinois. RV and tent sites, rustic and deluxe cabins, rental trailers, a pool, mini-golf and a fenced dog park, open from mid-April to mid-October.
Why it made the list
The nearest full campground to the city, and it has a fenced dog run and on-site trails, which makes an overnight with a dog straightforward.
Good to know before you go
Dogs are allowed but breed restrictions apply, so call to confirm which ones. Dogs must be on a leash no longer than six feet outside your vehicle, and are not permitted in the rental travel trailers; cabin pet policies vary between cabins. The park has a fenced dog park and walking trails. Details come from KOA and press coverage of the site.

House rules and verification
The pet policy above is summarised from the venue’s own published information and cross-checked against public listings. Policies change without notice anyway, so confirm the current one with the venue before you travel, and keep your dog leashed anywhere that is not a signed off-leash area. Read the full disclaimer.
