The Wadmalaw River is a tidal river forming part of the Southeast Coast Saltwater Paddling Trail in South Carolina. It is a coastal saltwater feature connecting the North Edisto River to the Stono River, with its waters flowing through the marshes and sea islands south of Charleston. Paddlers can access the river from several public landings. The Limehouse Boat Landing on the Stono River serves as a launch point for trips into the Wadmalaw, and the Cherry Point boat ramp near the terminus of Maybank Highway (SC 700) provides access near the river's confluence with Bohicket Creek and the North Edisto. The Walpole Dock area also has a boat ramp. The river is characterized by significant tidal influence, with a typical tidal range of 4 to 8 feet. Near Hollywood, high tides can exceed 2.3 meters (over 7.5 feet) and low tides can drop below 0.4 meters (about 1.3 feet). Timing a paddle with the tides is crucial; one local paddling group planned an outing launching before high tide at Limehouse Landing with the intent to paddle with the current both ways by riding the flood tide upstream and the ebb tide back. The river is part of a network of waterways that includes Leadenwah Creek, Bohicket Creek, and Wadmalaw Sound, offering extensive routes through tidal marshes. The area is noted for its solitude, with light boat traffic, especially south of Rockville. Paddlers should be prepared for open water conditions and wind exposure, particularly where the river widens. The surrounding landscape consists of expansive marshes, mudflats, and sea islands, providing habitat for wildlife such as redfish and trout. The river is part of the 295-mile South Carolina saltwater trail, which passes diverse coastal habitats and cultural sites. Facilities at launches are typically basic boat ramps, and paddlers must be self-sufficient. Water temperatures follow seasonal coastal patterns, being warm in summer and cool in winter.
