This is a very short after-work walk close to home… The Upper Cambourne Loop starts with the Upper Cambourne Track, which descends to meet the Cascade Track. It’s a wide fire trail that also forms part of the 80km Harbour to Hawkesbury route.
The Upper Cambourne Track meets the Cascades Track about halfway to The Cascades, a large natural pool where the Middle Harbour Creek and Frenchs Creek meets. I don’t continue down to the bottom, but head up the Cascades Track for a very short distance before turning onto a narrow walking track. One of the the many “unauthorised” trails in this area (and most likely intended as a mountain-biking trail), it provids an alternative and more interesting route back up to Cambourne Avenue.
Just before reaching Cambourne Avenue, there’s a rock outcrop that provides (almost) unobstructed views to the south, with the Sydney and North Sydney skyline visible in the distance,
From here it’s about 200m to the end of Douglas St, and then a few hundred metres back to the car a bit further down Cambourne Avenue.

This short bushwalk is different to the longer Cambourne Loop, which you can access via the Upper Cambourne Track or the Cascades Track and is all on firetrails. If you just want to visit the lookout point, it’s a few hundred metres from the end of Douglas St (St Ives).
