Sauk Lake South Boat Ramp is a concrete ramp located on the south shore of Sauk Lake in Stearns County, accessible via Bayview Drive.

The 12-foot-wide concrete ramp accommodates both motorized watercraft (gas, electric, or diesel engines) and non-motorized craft such as kayaks, canoes, and paddleboards.

Note that Sauk Lake contains aquatic invasive species including zebra mussels and flowering rush, so be sure to clean and drain your watercraft before and after use.
