Low Newton by the sea, Northumbria
Probably one of the most picturesque villages on the Northumberland coast, the small isolated 18th century fishing village of Low Newton by the Sea is owned by The National Trust, and is a ramshackle of small cottages. Stop for lunch at the 17th Century Ship Inn (originally known as the Smack Inn), before heading down to the beach. There is a good mixture of rock and sand here, so there is a good chance of finding a very diverse selection of shore life.
Rockcliffe, Kirkcudbrightshire, Scotland
Rockcliffe is a small seaside village along the north shore of the Solway Firth. A very picturesque seaside front looks out over two islands and lighthouse. The beach is a good mixture of sand and craggy rocks, perfect for razor clams and mussels
