Shark Bay
Located at the northern end of Nielsen Park, this beach faces north across Sydney Harbour. The sandy beach offers a swimming net enclosure[8], public toilets[9][10] and change rooms[11], showers[12] and is a popular place for people to simply relax. The beach is a focal point of Nielsen Park and also boasts a cafe[13]. Protected by the harbour, there is no surf at this beach. The beach is not patrolled. This is a lovely spot, with natural shade not far from the beach.
Nielsen Park Cafe
Open 8-5 daily, this historic cafe offers inside seating and a range of meals, including breakfast, sandwiches and hot food. This is one of a number of buildings in Nielsen Park which are available for functions. For further enquiries, contact 9337 1574. More info.

Turn sharp left: From the intersection, this walk heads directly away from the water[19] and up the path then steps[20], towards the grand building on top of the hill (not following the ‘Hermitage Forest Walking track’ sign[21]). The path heads past the sandstone toilet block[22] (on your right) and then at the top of the hill, the path bends to the right, in front of the ‘Greycliffe House’ information sign[23], coming to the driveway and a four-way intersection, in front of Greycliffe House[24].
Greycliffe House
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. More info.

The track soon bends left and heads high past Greycliffe House and a ‘Surviving the City’ information sign[27]. The track then gently winds through the bush over Mt Trefle (the high point, but not very high), coming to a ‘Greycliffe House’ sign[28] pointing back along the track, just near the back of the fenced workshop. Here the walk continues to generally follow the fence around the NP workshop. Heading along the side of the workshop, there is a view of some houses on Vaucluse Rd. At the front of the workshop, this walk turns left to follow the driveway down to find a ‘T’ intersection with a wider road (driveway).

Steele Point Cottage
Why not make a weekend of it? Built in 1880, this one-time gunners’ barracks has been restored as a one bedroom getaway. Managed by NPWS, you can hire this cottage (found on Steele Point) from $330 per night (two night min). Great for a romantic weekend away for two. More info.

Continue straight: From the intersection, this walk heads along the road a short distance, keeping ‘Steele Point Cottage’[37] to your left. As the road bends sharply to the right, the walk then comes to an intersection just past the fenced degaussing range, near a sign pointing to ‘Greycliffe House’[38].
Degaussing range
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), where metal ships passing over will be automatically de-magnetised. Why? Mostly to prevent the triggering of seabed mines. More info.

Turn left: From the intersection, this walk heads up the driveway, keeping the degaussing range fence just to your left[42]. 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]. At the end of this side trip, retrace your steps back to the main walk then Turn sharp left.
Steele Point Gun Emplacement
Construction of this initial emplacement took about three years and was completed in 1874. 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.
