About Group Campgrounds in Illinois

Group camping in Illinois offers diverse opportunities for families, friends, and organizations to gather in the state's beautiful natural settings, from the expansive waters of Lake Shelbyville in central Illinois to the mighty Mississippi River corridor in the northwest. The Prairie State provides an impressive array of group-friendly campgrounds featuring dedicated facilities designed specifically for larger gatherings, with amenities ranging from full hookups and pavilions to private beaches and team sports areas.

Best Time

The prime season for group camping in Illinois runs from late April through October, with peak demand occurring during summer months from Memorial Day through Labor Day when temperatures range from 75-85°F and all facilities operate at full capacity. Spring (April-May) and fall (September-October) offer excellent alternatives with milder weather in the 60-75°F range, fewer crowds, and spectacular scenery—spring wildflowers around Lake Shelbyville and fall foliage throughout the state's forests create stunning backdrops for group photos.

Tips & Recommendations

1Reserve early for Illinois group camping—popular facilities like Forrest W.
2Bo Wood and Sullivan Marina often book 6-12 months ahead for summer weekends, and most group sites require advance reservations rather than accepting walk-ins.
3Contact campground offices directly to discuss specific group needs, as many facilities offer customized arrangements for large parties including multiple adjacent sites or exclusive use of group areas.
4Bring extra-long extension cords and water hoses since group sites are often more spacious than standard campsites.
