Despite the throngs of people at the trailhead car park (Saturday 9 am) this was actually a reasonably quiet loop. I’m quite a fast hiker and completed it in just under 4 hours. If you are used to hiking or are otherwise fit,, you will probably agree that it is pretty easy terrain (though there are warning signs about its difficulty, so it’s important, as always, to really know your ability). Pretty views out to the sea (probably shrouded in fog in winter). The falls are not all that big, but are pretty. Diverse views and ecosystems. Definitely talk to one of the excellent staff rangers when you go in as they can give very clear instructions about how to start (I suggest counter-clockwise) in a way that is not obvious on the all trails or the paper map. I will definitely return and do this as a trail run! A warning: by 1 pm the car park was packed and rows of cars were waiting. Strongly encourage weekday or v early starts!
