A walk down memory lane. A 5.4 mile circular walk takes you from Porthcurno to Gwennap Head along some of the most striking scenery in West Cornwall. What is more, it is packed with highlights.

The starting view is of the lovely Porthcurno beach where the ‘sand’ consists of glistening broken shells. At the head of the beach is the little shed where the undersea cables come in, its doors open so that you can see the labels: Gibraltar, Lisbon … evocative names of far off places where the call sign PK would be instantly recognised. It is at the same time romantic and prosaic: to think that these famous places are connected with this little hut.
