Eugene has sent me three nice photos of the Abbot’s Cliff sound mirror, on the white cliffs near Folkestone.
The Abbot’s Cliff mirror is at grid reference TR27083867, between Folkestone and Dover. It is very easy to find, simply follow the tarmac path along the cliff top, and you can’t really miss it (it is a great big block of concrete, after all!). It is a five to ten minute walk from the Folkestone – Dover road.
