Campgrounds and RV parks near Grayslake, IL

Grayslake sits in Lake County, Illinois, about 45 minutes north of Chicago and inside the Chain O' Lakes region, the state's largest concentration of natural lakes. The area gives RV travelers quick access to state park campgrounds, private lakeside resorts, and river-adjacent parks along the Fox River corridor. Chain O' Lakes State Park anchors the region, covering roughly 6,000 acres and bordering Grass, Marie, and Nippersink lakes plus the Fox River that links the rest of the chain. Most campers base out of one of five nearby options: Fish Lake Beach Camping Resort in Volo for full-hookup RV sites and family amenities, Grass Lake Marina and RV Park for boaters, Turner Lake South inside Chain O' Lakes State Park for state-park sites steps from the water, Fox River Recreation for river access, and the Kenosha County Fair Association grounds just across the Wisconsin line for event and overflow camping. The mix suits weekenders from Chicago and Milwaukee as well as longer stays built around fishing, boating, and lake swimming.
