Porth Trecastell Beach (aka Cable Bay)

Porth Trecastell beach is a sandy beach tucked away in a cove below the burial chamber of Barclodiad y Gawres on the headland above.

The beach is also known as Cable Bay as this is the location where telegraph cables linking Britain with Ireland and America reach land.

The beach is popular for fishing, surfing, swimming, canoeing and windsurfing.

Parking but no other facilities although if you are lucky you may get an ice cream van.

Porth Trecastell Beach is dog friendly and allows dogs all year.
