Welcome to Roper Highway
Not far south of Mataranka on the Stuart Hwy, the mostly sealed single-lane Roper Hwy strikes 175km eastwards to Roper Bar, crossing the paperbark- and pandanus-lined Roper River, where freshwater meets saltwater. It's a gateway to remote and dramatic Limmen National Park. The road continues out to Numbulwar on the Gulf of Carpentaria coastline – you'll need a permit to take this road, including visiting Ngukurr, which is obtainable through the Northern Land Council in Katherine. Most of the highway is passable only in the Dry.
