The best way to see Sydney is by sea. I love to hop aboard an iconic Sydney ferry and enjoy the sea breeze in my face as we sail through the iconic harbour. Circular Quay is the hub of the ferry network (right next to the train station). Take your pick from 37 other wharves to sail to, ranging from Manly at the northern end of Sydney Harbour, through to Eastern and Lower North Shore suburbs, suburbs adjacent to the Parramatta River, the Balmain peninsula and Darling Harbour.
A few destinations the Sydney Ferries can take you to: Balmain, Double Bay, Manly, Parramatta, Taronga Zoo, Darling Harbour and Cockatoo Island. Honestly though, with a view like this, the journey can be even more beautiful than the destination.
