South Falls is the highlight of Silver Falls State Park, and due to its proximity to the city of Salem, is likely one of the most popular waterfalls in Oregon outside of the Columbia River Gorge. The falls are produced where South Silver Creek plunges 177 feet over a huge overhanging basalt cliff with a large pool occupying the bottom of the amphitheater. While South Silver Creek isn't nearly as voluminous as North Silver Creek, South Falls will still swell to impressive volumes during the wet season and is without question the most powerful waterfall in Silver Falls State Park during the high water season.
