The Narran Lake Nature Reserve is an inland freshwater wetland which was created in 1988. The Reserve is an important and protected area for for significant bird breeding and nesting and is not open to the public.
The area was a common meeting place for Aboriginal people for thousands of years and this is reflected in the current joint management of the park between NPWS and members from the local Aboriginal community. The reserve is rich in indigenous artefacts and places of cultural significance including the most extensive shell middens in North West New South Wales.
