Seven Sisters Cliffs

The Seven Sisters are a series of chalk sea cliffs on the English Channel coast, and are a stretch of the sea-eroded section of the South Downs range of hills, in the county of East Sussex, in south-east England. The Seven Sisters cliffs run between the mouth of the River Cuckmere near Seaford, and the chalk headland of Beachy Head outside of Eastbourne. The dips or swales that separate each of the seven crests from the next are the remnants of dry valleys in the chalk South Downs which are being gradually eroded by the sea.

Some of the cliffs and adjacent countryside make up the Seven Sisters Country Park, which is bounded on its inland side by the A259 road, and is itself a part of the larger South Downs National Park.
