Zelder Mill Park South Access Area serves as the take-out point for the Luling Zedler Mill Paddling Trail, located off Highway 80 (Magnolia Ave. ) across the river from the historic Zedler Mill.

The site features free parking and a boat ramp for easy exit from the San Marcos River; note that a dam is located beyond the mill, so paddlers must take out at this location.

This is the southern access point for a gentle 6-mile paddling trail suitable for family-friendly floats lasting 2-4 hours.
