Miles of walking and road biking trails connect directly to camp, making Camp Sullivan a functional base for active visitors who want to explore the Forest Preserves of Cook County without driving to a trailhead. The campground sits in Oak Forest, Illinois, managed by the county, and draws a consistent crowd of Chicago-area visitors using it as a staging point for city trips. Sites are wooded on the tent side, with decent shade, though some RV spots sit in full sun. Campers report hearing road noise from nearby roadways, offset by bird sounds and tree cover.
The sites are small. Reviewers with pop-ups and modest rigs have described feeling crowded, and the campground has only ten RV spots, with a 40-foot maximum. Lynn J. notes, "we are 35' and barely fit," calling it one of the larger sites. Site 8 has been flagged as more level than others. There is electric hookup at RV sites, but water access has been inconsistent across multiple visits. Several reviewers describe water being supplied via a garden hose from a cleaning closet rather than a proper hookup, and the dump station advertised on the campground's listing has reportedly not been available. The nearest dump station is approximately 20 minutes away, according to staff.
Bathhouse cleanliness is the most frequently mentioned concern in reviews, with reports ranging from adequate to genuinely problematic depending on the day and season. Toilet paper has run out between cleaning cycles, and shower maintenance has been inconsistent. On better visits, reviewers describe the bathhouses as fairly clean with newer facilities. The campground provides free firewood with stays, and there is a rock climbing wall on site that has drawn positive mentions, particularly from families.
Reservations go through the Forest Preserves of Cook County online system, which some campers describe as difficult to navigate. Double-booking has been reported more than once, so it is worth confirming your reservation by phone before arrival, though staff reachability can be limited. The entrance near the intersection of Oak and 147th Street can be hard to spot. RV drivers should avoid turning left toward the office on arrival; the RV sites are to the right at the fork. Pets are allowed throughout. Cell coverage is limited, with at least one reviewer noting weak T-Mobile signal. For a broader look at places to camp around Oak Forest, The Dyrt has additional listings in the area, including Walmart — Crestwood Supercenter to the northeast for campers needing a more utilitarian overnight stop.
