The eastern terrace's design was laid out in 1869 and remains the main feature of the garden. From the house's arcade (colonnade) you can view across bisecting pathways lined with flowerbeds to a view of Sydney Harbour. Through Cook's pines (Araucaria columnaris) and other trees you can see Fort Denison, Mrs Macquarie's Chair, Garden Island and beyond. Originally the view was wider to the east including towards the heads of the harbour). The Eastern Terrace has a central sandstone pond with its original stone fountain. Various garden schemes have been installed in the eastern terrace's formal garden borders flanking the central path.
