Built in 1816, Cadmans Cottage is one of only a handful of Sydney buildings that remain from the first 30 years of the colony. Over the years this sandstone cottage has been a water transport headquarters, a sailors' home and a water police station, among other things. It used to be beside the water, but since the construction of Circular Quay the harbour has 'moved' 100 metres away.

Now Cadmans Cottage houses a museum and the NPWS Metropolitan Branch Information Centre. Information is available on a range of guided tours, walks and activities available across national parks in the Sydney Region.
