Kristy and I walked a ton in Sydney. The Sydney Botanical Gardens are right in the city, over to the side and it's a huge, huge area which I had never walked through before. They are on a jut of land right by the harbour with incredible views. We entered from across the road from the NSW State Library, which is pictured below (the old bit of the library).
It was a truly beautiful walk through the gardens and when you get down to the bottom, the Opera House is right there! Incredible views and amazing being so close to the bottom part of the central business district. We barely touched on the gardens though, as it is huge!
A fabulous walk and better than pounding the city streets, which we also did plenty of last weekend.
