You can walk to it from the Lanthorn Library: EH54 6NY.
Info from Margaret:Google Map:
http://tinyurl.com/3mfhocpThere is parking space around the Lanthorn Community Complex – and there is a small pond next to the car park at the back (where the swan, cygnets and ducklings are) and then you can walk up and past the stone bridge (the original A71 route) to the big pond where the artwork is.
