Let me first state that we were extremely lucky with the day - wonderful weather for the season, no crowds at the attractions and no traffic.
About the itinerary: it is designed to capture in a day as much as possible about the area - some forest walk, many photo spots, steep railways, cable cars, aboriginal culture show, wildlife park and boat cruise. At the end of the trip, the Sydney Vivid festival also treated us to a light show as we were approaching the harbor. If you have two-three days for Sydney and surroundings, this is the trip to take. You can explore Sydney by yourself, but it would be impossible to cover this itinerary by yourself even if you would rent a car..
I want to especially emphasize how hard-working, funny and well-informed our guide Kat was. She was genuinely concerned that we see as many sights as possible, and managed to squeeze in at least 3-4 extra sights into the day, without feeling hurried in any of the locations..More
