Simpson Desert Regional Reserve is located in South Australia, 957 km (595 mi) north of Port Augusta. In combination with Simpson Desert Regional Reserve and Witjira National Park, it forms a protected area representing one of the world's best examples of dunal desert. A wide variety of desert flora and fauna are protected in a landscape of varied dune systems, extensive playa lakes, spinifex grasslands and Acacia woodlands. These trees soak up water from underground water springs.
