Walking in circles

We've always walked to the botanical gardens the hard way up to now - uphill all the way, leaving us totally exhausted by the time we get there. Today we realised that it's better to go all the way through Central, up the escalators, and then wend our way down the network of concrete flyovers and walkways, past a big gothic arch which is the entrance, well exit really, of a tunnel bringing water runoff from the hills, and in to the back entrance of the gardens. Much better!
We paid our usual visit to the various apes and primates, and then went across the road to the Park and back home in a neat circle.
