4 /5 Kim N: A moderate challenging and long track, grade 4. All trails advises it takes 4.5 hours..we managed to do it in 5 hours moderate pace with a lunch break.We started from Berowa Station from recommendation that its easier and finished at MT Kuringai Station. This track has no toilet facilities and the singage are poor in some areas, would not have been able to do without some guidance.This track is a good mix of bush, creeks and rainforest with some rock scrambling. Definitely a good work out and advisable to do in cooler months.
