Cuckmere Haven lies on the coast at the point where the South Downs meet the sea. Its dramatic chalk landscape with a characteristic cliffy coastline is constantly changing. The cliffs are being eroded at a rate of 30-40 cms every year.

Cuckmere's quiet beach, which is located within the Seven Sisters Country Park, is an area of great tranquility.

A path from the Seven Sisters Country Park Centre leads from the pebble beach through the Cuckmere valley.
