Anyone have a recommended tour operator for a day trip to Blue Mts...or....would it be more fun (as I suspect) to do your own (i.e. take the train and do whatever once you get there) outing? I did find one "eco friendly" operator with some nice choices of walks but they appear to be an "if you have to ask the price you probably can't afford it" type.
Will be in Sydney at the end of November.
Thanks
