This walk explores the bushy interior section of Nielsen Park. On this walk, you will visit historic Greycliffe House and the Steele Point Gun Emplacement. The walk climbs over the Mount Trefle summit. At just over 40m above sea level, I suspect most walkers will not consider it much of a mountain, but an enjoyable walk all the same. Most of this walk follows concrete and sealed paths, and there are some great harbour views on the second half of this walk.

Greycliffe House
Alt = 16 m
Greycliffe House was completed in 1851 by John Reeve, son-in-law to the explorer W C Wentworth. The house was unoccupied between 1898 and 1911, when it was taken over by the State Government and used as a baby hospital and Tresillian mothercraft home in to the 1930s. Many of the plantings are from this era. Today, the building is home to the Sydney Harbour South office of the NSW National Parks and Wildlife Service, and is one of few remaining examples of gothic architecture in Sydney.[25]More info

Degaussing range
Alt = 14 m
This degaussing range, found at Steele Point, was constructed in 1960 and is still operated by the Royal Australian Navy today. Degaussing is the process of removing (or at least reducing) a magnetic field. This degaussing range services four areas in the harbour (about 500m from the building)[39], where metal ships passing over will be automatically de-magnetised[40]. Why? Mostly to prevent the triggering of seabed mines[41]. More info

At the end of the driveway, the walk heads across the grass[43] to find the Steele Point Gun Emplacement[44] just behind the degaussing range. Beware of the unfenced drop into the emplacement[45]. (Retrace your steps back to the main track, then turn sharp left to continue along this walk.)
Steele Point Gun Emplacement
Alt = 7 m
Construction of this initial emplacement took about three years and was completed in 1874[46]. The sandstone pit once had a steel dome (to protect from shells) and was part of a series of gun emplacements protecting from the threat of invasion. Today, you will find a series of tall sandstone channels[47] and the circular pit where the main gun once stood[48]. A set of un-railed steps leads into the pit - please take care in the area, as the pit is not fenced.
