The Vernon River is a 12.5-mile tidal river flowing through Chatham County, Georgia, to the sea, characterized by expansive, open saltwater marsh environments. Paddlers describe it as "big water," indicating significant exposure to wind and fetch. A primary access point is the Vernon River Bridge, which offers easy access to boat ramps. Another documented launch is from Skidaway Narrows at Butterbean Beach, which provides a beach launch and parking. This launch point actually puts paddlers on the adjacent Skidaway River, requiring a paddle through connecting waterways like Moon River and a Burnside Island canal to reach the Vernon River proper. Tidal currents are a major factor for trip planning. One account details paddling on an outgoing tide, which provided assistance against the wind, and specifically timing an arrival at a destination for low tide and slack water. The river is part of the extensive Southeast Coast Saltwater Paddling Trail, an 800-mile route connecting coastal waters from the Chesapeake Bay to the Georgia-Florida border. A notable destination along the river is Green Island, a small island featuring a maritime forest with live oaks, pines, and cabbage palms, though it is privately owned. The island also has historical significance, containing Civil War-era fortifications. Wildlife evidence includes a robust population of wild pigs on Green Island. The area is used by motorized boats, as it connects with the Atlantic Intracoastal Waterway.
