The South Shore Unit boat ramp at Choke Canyon State Park features a six-lane improved ramp with lighting, located four miles west of Three Rivers on Texas Highway 72.

Amenities include restrooms, cleaning stations, live bait, parking, and picnic areas, though a park entry fee is required and the facility is day-use only (closed 10 pm to 6 am).

Note that water levels are historically low (around 16% capacity), making launching challenging; shallow-draft boats like kayaks and canoes are recommended, and launching is at your own risk due to soft sediment and submerged hazards.
