Another one of Sydney Harbour's many small forts, built to prevent a WWII attack from the Japanese. You'll also have some impressive harbour views from the hill.

A 9.2-in gun barrel display. Nothing too special about it, but it is worth a quick look.
A cemetery for the third class passengers from the quarantined ships quarantining at the North Head Quarantine Station.
A harbour facing lookout, facing the Sydney skyline, including the harbour bridge, the Sydney Opera House, and the Sydney Eye. You might see some of the harbour islands although they may be obstructed by the trees.
A lookout overlooking the ocean, but also overlooking the flora and fauna nearby.
Fairfax Walking track
A short 700-m loop trail, which gives picturesque views of the Harbour, the ocean and the former battery. Suitable for most ages, however, if you're going with young children, make sure they do not pick up things on the ground. These may be UXO's and it is a federal civil offense to even move them, and the penalties are hefty.
A bike path, but there's more people who walk this track.
