@Antoine If it helps, twelve months ago I'd have been standing in the lion enclosure to get this photo (some curators would probably have encouraged that).
@SMR I know where you were for the photo but it sounds strange for me to see the change between before and now.
I must come back again to see on my own
Yes, it does feel a bit strange. I guess the steep hill would be to the left and then the path does an abrupt kind of U-turn (around the lion exhibit) off to the right of the photo towards the building in the photo here. Am I remembering correctly?
@amur leopard There is a wooden ramp - The Bats Bridge - but it's not steep as it's wheelchair-friendly. It'd be over your left shoulder from the viewpoint of this photograph.
Many years ago there was a set of steps up to a high-level viewing platform, but I doubt you're that old.
