The boat slips away from a ferry-scarred wharf and the city contracts into a horizon of steel and water. Salt and eucalyptus sharpen as the skyline peels open: the arch of the Harbour Bridge, the scalloped sail of the Opera House, then smaller, less-known shorelines that seem to keep their secrets by choice. On this three-hour circumnavigation, the islands of Sydney Harbour—their sandstone faces, scrubby natives, and quiet coves—become the quiet antagonists to the city's bustle. The tour drops anchor for a picnic at Lavender Bay, where kayaks and lunch blankets share space with a moored view of Luna Park’s painted grin.
