Weekends on Sydney Harbour can be very crowded. If possible organize your visit for a weekday.
Ferry rides on the harbor can be taken anytime of year. Summer and spring are a good time do this if you want to swim.
In the summer, a day at one of Sydney’s lovely harborside beaches is one of the best things to do in Sydney with kids. Take the Ferry and sit on the outside decks to catch the views. Children will love the ferry ride, sitting with the wind in their hair and watching the other boats pass by. Cool off with a swim at Watsons Bay Beach, then head to Watsons Bay Hotel for a meal. Or buy just the ingredients for an impromptu picnic! This itinerary allows you to experience Sydney like a local.
