Walk 12A Berowra to Thornleigh
With new Great North walk deviation around Rifle Range
Walk times are based on continuous walking with several 3-4 min stops
This is now the official Great North Walk due a to more than zero risk from activities of the Hornsby Rifle Range and the subsequent closure of a section of the original Bicentenary Heritage walk along Berowra Creek between Fishponds and Steele Bridge. The deviation adds 1.70 km. in length and 38 minutes in walk time with most of the deviation along residential streets and an additional 110 meter ascent and descent.
If ‘zero risk’ applies to Rifle Range activities, then the Range itself needs to close. There is no ‘zero risk’ in life
Most of this walk is on The Great North Walk and along Berowra Creek valley from tidal to rapids .
