Cay Creek is a tidal waterway in eastern Liberty County, originating near Midway and meeting the coast near Harris Neck. Originally known as Salter’s Creek, it was renamed Cay Creek for Raymond Cay, Sr. (1805-1883), who owned a plantation near the present-day Cay Creek Wetlands Interpretive Center. The relatively short waterway features an amazing variety of ecosystems, including upland forest, open wetland, tidal swamp, brackish marsh, and finally tidal creek.
