  1. I did this walk and it was really great. It is not marked at all and the local instructions are not the best. The view from the brothers rocks is amazing and we saw a lace monitor and a koala come down a tree, walk across the ground and climb another. If you walk it in the direction written above there is a VERY steep downhill section towards the end.

    1. Thanks for the feedback. I’ll change the hours to 3-4. Last time I did this was with a group of kids so we spent a lot of time exploring the rocky outcrops.

  2. We did it couter clockwise and it was nice. The steep part before the Four Brothers was enjoyable. It was great to take our lunch at the Four Brothers as the view really worth it.
