The Salem River in New Jersey is a tidal river offering a flatwater paddling experience through extensive marshland corridors, primarily within the Supawna Meadows National Wildlife Refuge. The river's character is defined by its quiet, pristine marsh environment with tall grasses, but it is a dynamic system where trip success hinges on careful tide planning. The current direction changes with the tide, and water levels can drop significantly, leaving smaller refuge channels impassable and muddy at low tide. Paddlers must consult tide charts before departing to time their trip, often planning to paddle against the current first and return with it. A key launch point for accessing the refuge is from the south side of the river, across from the refuge's southern end, such as at Sinnickson Landing Road. Another documented public boat ramp is located on Route 540 in Mannington Township. The main paddling route involves launching and heading east upstream before returning, or crossing from the launch to enter the refuge's network of channels on the western side. These channels, while beautiful, are numerous and can look very similar, increasing the risk of becoming disoriented; bringing a detailed, up-to-date map or aerial photograph is strongly advised. Wildlife viewing is a highlight, with notable sightings including bald eagles—there is a large nest visible on a power line tower near the refuge—and various waterfowl. The area is having few bothersome insects. Non-scenic power lines cross the area but are easily ignored. The water body is shared, so paddlers should be aware of other boat traffic, particularly near launches and the main river channel.
