Sydney Harbour - Salt Water Ferries - I just love the old yellow ferries. I am told the white new sleek ones are more expensive and to my mind less romantic. You can get a Daytripper pass that lets you combine train travel with bus and ferry and in that way negotiate the whole harbour with one ticket regarless of the mode of travel in that portion. On New Year's Eve watching the fireworks under the Harbour Bridge it was amazing there will no accidents with all the small craft mixing in the high speed ferries and my personal favourites the old yellow ferries.
