A 17-minute ferry ride from Circular Quay whisks you to Watsons Bay, where a mellow park flanks a cluster of cute harbor beaches. Opposite the wharf, two tempting restaurants beckon for seaside feasts. Upscale Doyles serves more formal fish and seafood, with a bistro/kiosk by the jetty for cheaper takeaways. Neighboring Watsons Bay Boutique Hotel has a multilevel beach club terrace out front, where beer-battered fish and chips, calamari, burgers and cocktails attract a party-ready crowd (DJs spin on Saturdays). Wander through the village to ultra-pretty Camp Cove for a swim before or after, with vistas of the city skyline if you paddle out a little. A scenic stroll past a hidden nudist beach brings you to Hornby Lighthouse at the harbor's south head. You can also stride across to the Gap for wild ocean views, especially amazing when the Sydney to Hobart Yacht Race departs from here on Boxing Day. For a longer walk, history buffs can head past Parsley Bay to colonial Vaucluse House. Afterwards, take a dip at seductive Shark Beach in Nielsen Park (home to a convivial café), before continuing along the harbor-hugging Hermitage Foreshore Track to Rose Bay for the ferry back to town.
