Great for families, or anyone who enjoys a touristy experience. This tour is on a bus, and feels very much like a field trip I took in school. Our driver was very kind, but had to cater to a bus of 30 people, and had difficulty engaging everyone. Not recommended for anyone who wants a more personalized experience.
There is really no better way to see Sydney Harbour. We got a tour of downtown, the Opera House, the beaches and the surrounding area in less than half an hour! Take this tour early in your visit to get the lay of the land.
