Limmen National Park, announced in 2012, is the second largest in Australia covering 10,000sqkm in the Northern Territory. Located about 600 km south-east of Darwin on the Gulf of Carpentaria, the park incorporates wetlands, sandstone structures and numerous rivers, including the Limmen Bight River from which the park takes its name. A major attraction in the park are the 'Lost Cities'—sandstone rock formations resembling tall apartment blocks.
