What can I do in this reserve?

The Mulligans Flat Nature Reserve is used for walking, running and cycling. Bird watching is also very popular. Ranger guided activities are organised within the Mulligans Flat Woodland Sanctuary.

A walking trail with track markers has been established around the perimeter of the offset area. This track links with an urban park within the adjacent Bonner residential area and ends at a car park accessible from the Mulligans Flat Road.

This track has been placed to improve access into the Mulligans Flat Nature Reserve for the local residents, while avoiding any direct impact on the golden sun moth habitat within the offset area.

Dogs and horses are not permitted within the Mulligans Flat Nature Reserve, including the offset area.
