Penrhyn Hill ... No
Here is a pic taken from the other end of the path, so looking back to where I took the first pic - does it help? The two pics are taken 50 metres apart but in opposing directions!
I will reveal the answer tomorrow night (Friday) but I'm sure someone will get it before then. I am fairly certain you will all have been there! SteveH has been very warm with one of his guesses!
