I've just been on site. There are two paths leading up to this area of the Botanical Gardens. One you can only just make out from above and below, which consists of steps and inclining footway. This one is closed off. I've changed the steps bit to this path. Then I have added another, veering off a bit further to the west, with a bridge to go around a large tree. The situation should now be more or less correct (alignment might not be correct).
