The Mackerel and Basin Loop joins the Mackerel Track and Basin Track at West Head with an off-track section along the coastline. It passes some Aboriginal sites and offers some nice views, but the Basin Track is pretty dreary.
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
An off-track walk from Dargan (on Chifley Road) to Goochs Crater in the Blue Mountains.
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 partly off-track walk along the Salvation Loop at West Head, to explore Wallaroo Hill (a small hill at the start of the Wallaroo Track).
The Bombi Moor Circuit a fairly exposed route through the coastal heathland of Bouddi National Parks, with side-trips to three headlands and the picturesque Little Beach. Best walked outside summer.
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.
A circular bushwalk in Popran National Park which combines the Mount Olive Trail, Hominy Creek Trail and 248 Track. The destination is the beautiful Emerald Pool, and there are multiple Aboriginal engraving sites along the route.
