Very interesting information given, thanks. We are coming over to Oz in December to Melbourne, and then flying up to Sydney on or about the 23rd January, we hope to visit the Blue Mountains but know nothing about them! sorry guys!, there will be 6 of us and we would like to spend a day or two visitng the Blue Mountains... upon researching the area seems massive... so what do we do? where do we go? Any information would be appreciated.
