Everything about the Seven Sisters, in one place
The definitive guide to England’s most iconic chalk cliffs — geology and wildlife, walking routes, live conditions, safety, photography and how this coast compares to Dover, Beachy Head and beyond.
A complete, trustworthy picture of one stretch of coast
The Seven Sisters are a series of chalk sea cliffs on the English Channel coast of East Sussex, southern England — stretching between Cuckmere Haven and Birling Gap within the South Downs National Park and the Seven Sisters National Nature Reserve, designated in 2026. The cliffs are free to walk year-round, roughly 90 minutes from London, and neighbour Beachy Head — Britain's highest chalk sea cliff. This hub brings together every guide on this coast: geology, wildlife, walking routes, conditions, safety, photography and destination comparisons.
The Seven Sisters are a series of chalk sea cliffs on the East Sussex coast of southern England, between Seaford and Eastbourne. They form the heart of the Seven Sisters National Nature Reserve within the South Downs National Park, and sit beside their taller neighbour Beachy Head. The white chalk was laid down on a warm Cretaceous sea floor around 70–90 million years ago; constant erosion keeps the faces brilliant white and is also why walkers must keep well back from the edge.
