South Branch Lake Boat Ramp in Seboeis Plantation offers a hard-surfaced 10-foot-wide ramp with a 40-foot length and 11% grade, suitable for trailered boats accessing this freshwater lake.

The facility provides 12 rig parking spaces and seasonal toilet facilities, though it has no boarding floats available. Vehicle parking is limited, making this a modest-sized access point best suited for smaller boat operations.
