Topham Trig is on top of the scrubby Topham Hill in West Head, which has a number of Aboriginal engraving sites. The trig is reached by a bush-bash from West Head Road, following the ridge up to the highest point. The steel post embedded in a snall concrete base was installed in 1976.
There’s not much left of the original Topham Trig Station (TS5653), which dates back to 1882. The rusted vane lies a few metres away, with the “Topham” nameplate still attached, but there’s no evidence of a rock cairn.
Names carved into the sandstone date back to 1939 – when the trig was most likely a lot easier to reach!
There are views of the ocean in the distance from the trig point, and nice views of Pittwater and the Barrenjoey Peninsula from lower down the ridge.
