The Pylons Loop from Warrimoo to the St Ives Wildlife Garden is a varied and partly off-track loop. It links the Warrimoo Track, Ryland Trail, Callamine Trail and Showground Trail and makes use of a number of fire trails that service electricity pylons.
The Cowan Track and Wilkins Track are both accessed via the Perimeter Trail in Duffys Forest, providing easy access to two lookouts over Cowan Creek and an Aboriginal engraving site.
A pleasant one-way walk from St Ives (via the Warrimoo Track) to Mt Ku-ring-gai station. It follows Cowan Creek and traverses Bobbin Head, where you can stop for a coffee or snack.
The Wallaroo Track at West Head is accessed via the Salvation Loop, and leads to a rocky platform with nice views over Cowan Creek.
The Curra Moors Loop is an alternative to doing the full Royal National Park Coast Walk. The circular walk is a shorter option that takes in some of the spectacular coastal scenery.
