A forested campground near fishing, hiking, and mountain biking. RV fit varies by site.
South Marcum Campground sits on the lakeward side of Rend Lake in southern Illinois, where low-lying woodlands open onto broad water views and shoreline access for anglers. The campground's lakeshore location makes it easy to fish from the bank right from your site, launch a boat at one of the many nearby ramps, or spend the day on the water sailing, skiing, or paddling.
Length limits vary by campsite.
Showers on site.

Months with fewer than 30 reservations of that kind are left blank. Sites where nearly every booking was made the day of arrival (pay on arrival) are left out. Closed seasons, windows not yet released for booking, and currently unavailable nights are separate from this history.
Based on Recreation.gov reservations, FY2015–2025 (44,347 reservations in the years scored). Counts reservations made, not nights actually camped: cancellations aren't in the data, and nights a site was closed count as not booked. FY2020–21 (COVID) are left out of the scores.
