The Limmen Bight River is a tidal estuary located within Limmen National Park in the remote Roper Gulf Region of Australia's Northern Territory. It is a coastal saltwater feature, with its character defined by the Gulf of Carpentaria's significant tidal movements. The Savannah Way road crosses the river close to where tidal influence is still felt, and this concrete river crossing serves as a primary public access point for paddlers. On a big tide, water floods over this crossing, pushing upstream, indicating a substantial tidal range that dictates paddling conditions. The river provides access to the broader Limmen Bight, a shallow marine bay. The surrounding country includes broad plains and low, rocky sandstone ranges, with the coastline featuring sea, islands, and coastal areas. The region is part of the sea country of the Marra and Yanyuwa peoples, who identify as Saltwater People, and has a history of visitation from Macassan fishermen. For paddlers, key considerations are the strong tidal currents, especially around the narrow rock channel at the road crossing, and the remote, exposed nature of the bight. The Limmen Bight Fishing Camp provides a base with easy access to the river. The park is remote, accessed via four-wheel-drive tracks like the Nathan River Road, and facilities are limited. The water body is part of a marine park, and paddlers must be aware of any zoning regulations that apply. The aesthetic is one of a vast, flat coastal landscape with pandanus-lined creeks in some areas.
