Sydney Harbour is one of the most beautiful natural waterways in the world, with ferries, yachts and tall ships criss-crossing the sparkling blue waters. Aboriginal people have a deep connection with the harbour, dating back at least 50,000 years. Take a ferry from Circular Quay to Manly or Watsons Bay. Cruises depart from the quay and Darling Harbour. You'll also enjoy stretching your legs on delightful walking trails around the harbour foreshore.
