Described on one blog as “a small mound on the Blackheath to Perrys Lookdown fire road”, Hat Hill is the site of Hat Hill Trig – with the top of the rocky hill offering some sweeping views. The trig itself has seen better days – the concrete base and metal stand remain, but the vanes are gone – probably sheared off by strong winds.
The short trail to the top of Hat Hill is worth it for the almost 360-degree views: looking to the east across Perrys Lookdown Road is Lockleys Pylon, Mount Hay and the Grose Valley.
To the south is a view of the Griffith Taylor Wall, on the opposite of Govetts Gorge.
Getting to Hat Hill Trig
Although the track to the top of Hat Hill is easy to miss, it has a small carpark along Perrys Lookdown Road. The start of the walking trail is about a 5.4km (7min drive) from Blackheath.
A rough walking track continues onto Bald Head, an informal lookout on the edge of the cliff.
