A somewhat uninspiring but pleasant bushwalk between Gordon and Thornleigh, which is mostly along the Lane Cove Valley Walk (which is part of the Great North Walk).
Sams Creek Loop combines Sams Creek Trail and the Berkeley Fire Trail in Berowra, to create a pleasant bushwalk that avoids the crowds.
A boat trip along Cowan Creek, exploring some of the Aboriginal rock art and early European settlements along the creek.
A loop walk in Marramarra National Park which descends to Marramarra Creek via the Smugglers Ridge Track, and returns along the Marramarra Ridge Trail. A pleasant but not particularly exciting walk.
A fairly demanding walk along an undulating ridge to Taffys Rock, a large sandstone platform that provides panoramic views over the Hawkesbury River and Cowan Creek
A short bushwalk along Gundah Ridge, with some nice views over Berowra Creek
The Myall Trail is a short firetrail that leads to the end of a ridge in the Ku-ring-gai Chase National Park, with views over the park.
A short off-track walk in Berowra Heights, exploring towering cliffs and weathered caves
A nice loop walk from Apple Tree Bay, combining a “secret track” up to the ridge with the the Mt Ku-ring-gai and Berowra Tracks. Some nice views and interesting caves and rock formations.
The Pogson Trig Loop combines the Blue Gum Walk, Pogson Trig Trail, Quarry Firetrail and Benowie Track (Great North Walk). Sections of this loop require approval (as it crosses behind the Hornsby rifle range), or the walk can be accessed from both Westleigh and Hornsby to avoid the closed sections of track.
