Absolute “insider tip”. One of the most beautiful beaches in the region if not the whole of the UK

This beach is made up of pebbles and exceptionally dark sand made from crushed grey slate. The slate gives the water in the "Blue Lagoon" its bright deep blue colour. To the north of the beach is a lovely little harbour - an open-cut quarry that is also wheelchair accessible. Be careful: there are strong currents here.
