Walk: Tahmoor Canyon
Tahmoor Canyon is a hidden gem of southern Sydney bushland. Its two key features are the striking canyon of the Bargo River with pools such as Mermaid Pool, and the scarp of the Bargo Fault. This escarpment is part of the Lapstone structural complex, normally characterised by monoclines, but this is as beautiful an example of a true fault scarp as you’ll see anywhere. The flora is Hawkesbury Sandstone bushland par excellence, with a veneer of Mittagong Formation shale/sandstone and its varied woodland flora. It has an abundance of species and last year we saw spectacular flowering of Pseudanthus pimelioides, a shrub that you rarely see in North Shore bushland. We also saw lots of tiger orchids and several species of Prostanthera. Purple dampiera Dampiera purpurea are bigger and more spectacular here than anywhere else I’ve seen them.
Getting there: From the North Shore take North Connex (or Pennant Hills Road) to join the M2, then the M7 and M31. Follow the latter, the Hume Motorway, to the Avon Dam Road interchange (the next major interchange after Picton Road). Turn right and then right again after a short distance onto Arina Road. Follow Arina for 7 km, then on descent to cross Rockford Bridge turn left then immediately right to a long, gravelly car park. If you have inadvertantly crossed Rockford Bridge do a uey. Total distance from Pearces Corner is 110 km.
Refreshments: provided after the walk
