If you look at the trees, especially those in front on bends you do get some idea.
It was SO steep in there, I thought we were going to need a ladder!
I do remember going back to 1st gear on one of them after getting a sizable run up!
I remember doing that road for the first time many years ago (80's). We had done the rest of our trip in a mate's VK Commodore, but he didn't want to take it up there so we hired a Suzuki 4wd in Cairns for the run to Cooktown. Neither of us had done much 4wding at the time and just assumed it would go anywhere. There were several hills that had us slipping around a bit, but I do remember one in particular where we had 4 attempts and were seriously starting to doubt that we'd get up it. It was bone dry and this was on the main road
. We needed a sizable run up even in 4wd as the Suzuki, much like a Moke, was very light and just kept slipping on the loose gravel. I had not long come off my P Plates (19 years old) so was of course an expert driver, which made it very hard to understand at the time
