I stopped at the Tingle tree 'Tree Top Walk' Valley of the Giants area, but did the free ground guided "Ancients" walk instead. In the discovery center they had HUGE insect models. I got a map to the "Big Tingle Tree" there. I drove a fair bit of gravel to see it and walked some more of the Bibbulmun Track there. There was a way to steep-not quite mudslide section of the gravel road out (one way). I made it.
