I hadn't been here since 1981 & really enjoyed it. We got a combination boat & zoo ticket which should have included a sky rail ride as well but the booking office at Circular Quay did not seem to be aware it was out of action however we were transported by bus. We found the layout good, the exhibits & surroundings for the animals very good & the animals looked relaxed, happy & healthy in their surroundings. The scenery over to the city is really nice . The timetable/map clearly sets out the show times etc so you can plan your day, the bird show was very good. We visited on a quiet mid week day & it was very pleasant wandering around & not having to fight the crowds, especially in the cafe. The food selections were good but were mostly closed by 4 pm when we were looking for something for afternoon tea.
There are new exhibits being constructed at present & we found by careful planning we walked from the top down arriving at the ferry terminal in plenty of time but we got to see all of the exhibits - some animals I hadn't seen before. Spend a whole day here as there is plenty to see . It may be costly, but for a whole day of entertainment it is generally very good value. The zoo appeals to all ages & they have made it very assessible for all abilities.
