Some technical rocky sections with nice singletrack thrown in. Riding from Linksley Road, you will love this rock and rolling, scenic ride parallel to the verdant fern-lined Castle Hill Creek. Singletrack opens out onto a firetrail /neglected Hills Council Cyclepath in Fullers' Road Reserve, hugging the bottom of sheer rocks at the hem of suburbia. Look out for the pipeline. Ride or portage down to some choice singletrack running parallell to Cattai Creek popping out at the waterworks. If teccy stuff is not for you, continue along the dirt cyclepath which then opens out onto a short stint on tar, and you are now riding parallel to Cattai Creek and straight for the Waterworks. Turn left onto the single track at the waterworks fence. The track loosely follows the perimeter of the waterworks. It is very technical, and only elite mountain bikers will be able to ride the whole thing. Keep your weight far back off the saddle if rolling down the rock steps. Turn left over the footbridge to the BMX track. From here, there are plenty of short, winding single track circuits in bushland around most sport fields to explore and call your own. None of them are ever groomed, but surprisingly for Sydney, many of them are actually marked ! They are all rocky, rutted and intersected by tree roots- the most excellent stuff to make mountain bicycling here, amongst the best Hills District currently has to offer!Lovely playground for the kids with water bubbler between Cedar Grove Road and Field 6. Coffee and toilets at Local Bean Café, Knightsbridge Shopping Centre. Nearest bicycle shop is 99 Bikes, Victoria Road. CHBMX is a very active club, welcoming new members of all abilities to their school holiday skills sessions and weekend race events.
