I was up there with fellow North Shore Rescue members in May 2016 and we added handlines along each bank and marked a crossing high up on the slide.
I was up there last Friday. We put some landlines in on the slide at 450m. I notice you have pictures of a second slide a little higher up? Do you remember f that one needed landlines as well? I am putting these in for North Shore Rescue and we need to be able navigate this trail in the dark.
