They show an amazing slice of Britain’s history over many million years. Here is the geology - White Chalk from the Upper Cretaceous era forms the top layer, followed by a layer of limestone, known as red chalk from the Lower Cretaceous period formed over a period of 15 million years and finally beneath is grey/green Carstone. As both the red and white chalk contains fossils the beach below is a magnet for keen fossil hunters. On top of the striped cliffs is Hunstanton North Promenade, which has lovely gardens and walks overlooking the sea.
