Campgrounds and RV parks near Prairie Grove, IL

Prairie Grove sits in McHenry County in far northern Illinois, roughly an hour northwest of Chicago and within easy reach of the Fox River corridor and the natural lakes that define this part of the state. RV renters use it as a base for water-oriented camping, with several private resorts and a large state park campground inside a 30-minute drive. The closest anchor for public camping is Chain O' Lakes State Park in Spring Grove, which borders Grass, Marie, and Nippersink lakes and connects to the Fox River. The park covers more than 6,000 acres across the state park and adjoining conservation area, with over 230 campsites spread across multiple areas, including Turner Lake South. Private options nearby include Fish Lake Beach Camping Resort in Volo, Grass Lake Marina and RV Park, and Fox River Recreation, plus the Kenosha County Fair Association grounds just across the Wisconsin state line. Most sites are within a short drive of grocery, fuel, and dump-station services in McHenry, Antioch, or Fox Lake, which makes provisioning between stops straightforward for RV renters.

Chain O' Lakes State Park reservations are handled through the state's ExploreMoreIL system at camp.exploremoreil.com, or by phone at 866-716-6550. The park has Class A-Premium sites in the Honey Suckle Hollow and Fox Den areas, and Class B-Premium sites at Turner Lake South, Prairie View, and Mud Lake East.

Private campgrounds such as Fish Lake Beach Camping Resort, Grass Lake Marina and RV Park, Fox River Recreation, and the Kenosha County Fair Association take reservations directly through their own websites or by phone.
