Braidwood Lake South Boat Ramp (County Line Road Access) features a four-lane concrete ramp with 35 car/trailer parking spaces plus an additional 75+ car lot adjacent to the ramp area.

This south access point is the primary launch facility for the 2,640-acre lake, though boaters should note that boats under 14 feet are not recommended due to the lake's steep drop-offs, rock piles, and hazardous conditions—a topographic map is strongly advised before launching.
