Sydney's Circular Quay
is a logical starting point for a walking tour of the city as this is the most accessible transport hub for ferries, trains and buses. From here, you could, for instance, take the walking tour to The Rocks
. This time, we start from here for a walking tour -- to the Sydney Opera House and the Royal Botanic Gardens, then through a number of other Sydney attractions -- to Hyde Park in the heart of the city. From there, if you wish, you can continue the tour to Darling Harbour.
