Big Ducky Waterhole
The service trail loops around the top of the Big Ducky waterhole and there is a nice rock overhang in which to break. Is also a popular bird watching area. Unfortunately, recently there has been large quantities of rubbish in the area. (If going down to the waterhole please consider carrying out some of the rubbish if every walker carrys out a bit it will make a difference)

Whale Rock
This is a large boulder that looks eerily like a whale, complete with eye socket. It is a good place to break and climb around the Rock.

Conscript Pass
Conscript Pass is a small sandstone pass between the Lane Cove River and Thornleigh, on the Great North Walk. During the 1930s, some stone steps were built through a cleft in the rock as part of a public works program, in response to the depression. The pass has two main engravings. Firstly 'Conscript Pass' is followed with a downwards pointing arrow and a series of initials and numbers. On another wall (that you face when walking up) is engraved 'B Stevens' followed a surprisingly good caricature of the then Premier of NSW, Bertram Stevens. Stevens (later knighted) replaced Jack Lang in 1932 as Premier of NSW, when Lang was dismissed by the Governor (just two months Lang after opening the Sydney Harbour Bridge).

Thornleigh Oval
Thornleigh Oval is found at the intersection of Handley and Ferguson Avenues, Thornleigh. There is a large playing field, tap water, public toilets and some shelter in the awning of the club house. The oval has a car park, and a number io signs for the Great North walk and other local tracks.
