I found Walk91 and the Great Ocean Walk by Internet search.
The Great Ocean Walk was stunning! Loved it all except crossing the blowhole by myself!
My driver was excellent flexible, reliable and informative. Make sure if you go to the tavern/pub to try the chicken with pesto and Mediterranean vegetables!
I prefer to walk in a group but enjoyed the personal challenges of walking alone this time. It was a memorable experience and thanks for helping me achieve this.
