Aberffraw: was once an important port, but the estuary gradually silted up, leaving the present coastline of sand dunes. The dunes range as high as 30 feet and more. The sculptured sand is stabilized by mar-ram grass near the sea, and patches of sea holly can be found in autumn. The buildup of dunes has also created the inland lake of Llyn Coron.

Cornwall: with its whitewashed seaside villages and greener-than-green countryside dotted with Celtic ruins, the Cornish peninsula is a hybrid of historical attractions and natural beauty. From its subtropical gardens to its steep cliffs that cascade into the Atlantic, Cornwall has an island feel, and is, in fact, almost an island, nearly separated from the rest of Britain by the Tamar River.

The Ceredigion Heritage Coast is divided into four separate sections totaling 21 miles, including several nature reserves and marine conservation areas, a testament to the wide variety of bird and animal populations it supports. A partial list of birds to be seen includes cormorants, coughs, raven, peregrine, and buzzard.

The coast has everything; rugged headlands jutting out into the sea, small fishing villages and harbors, sandy beaches, isolated coves, and cliff top grasslands. Just as importantly, the coast is sparsely visited, leaving visitors with the peace and quiet to explore without crowds. There are traditional seaside holiday centers at New Quay and Aberystwyth, but away from these areas the coast has plenty of secluded corners.

Penbryn, near Aberporth, boasts long, sandy beaches backed by sand dunes and woodland trails along the coast.

The headland at Dinas is one of the most spectacular along the Pembroksehire Coast (which is saying a great deal). At 463 feet in height, the cliffs at Dinas Head provide excellent views across Fish guard Bay to the south and Newport Bay to the north. The headland is under the care of the National Trust.

Dorset is a county of great beauty, a land of contrast and breathtaking scenery. It is one of the maritime counties of southern England, fronting the English Channel which separates the United Kingdom from mainland Europe. Its coastline extends some 140 kilometers from Lyme Regis in the west to Christchurch in the east, and offers a selection of the finest sandy beaches to be found in the British Isles.

This coastline is notable for its color, as well as its ecological value; the red Devon sandstone of the cliffs is broken by the startling white chalk of the Beer headland. The cliffs are split by deep wooded combes and isolated coves and topped by heath and grassland.

Exmoor Heritage Coast: this is England's highest coastline and the striking "hog-back" cliffs tower over the Bristol Channel. The cliffs are sliced by steep, wooded combes. In some places oak woods have grown right down the cliffs, bringing the rare sight of woodland and seashore life mingling on the pebbled beaches.

Lynton and Lynmouth are like twins, one village complementing the other. Lynmouth is wedged between a steep cliff and the ocean on North Devon's coast, while Lynton looks down from the 500ft (152m) high cliff top on her twin. The views from either are glorious. You can see, on a clear day, across to the Welsh coast.

But proximity is about all these twins have in common. Lynmouth is a traditional fishing village with stone houses, and Lynton is a Victorian-Edwardian village, many of its homes turned into seaside villas and hotels.
