I love the zoo, but it is a full day, and it is quite a bit of walking, almost regardless of which zoo you go to. I love that Taronga is on a hillside and you start by catching a cable car up to the top and then the day is just wandering down and across the hillside. It still is a big day for me though, with a recovery day needed afterwards, but it's nicer than Perth or Adelaide which are all walking, Perth in a big loop with some side paths, Adelaide in a long narrow loop.

I grew up in the country, so paths were sometimes wherever we made them. Was fun, but I much prefer having something semi-permanent at least these days
