I'm sorry, but there seems to be a misunderstanding. Kapa Beach in Seaford, United Kingdom, doesn't seem to exist. Seaford is a coastal town in East Sussex, England, known for its beautiful coastline along the English Channel, but there's no record of a "Kapa Beach" there. Seaford Beach, which is a shingle beach, is popular in the area and offers a stunning view of the Seven Sisters cliffs, a series of chalk cliffs that are part of the South Downs. Activities at Seaford Beach include walking, swimming, fishing, and enjoying the natural scenery. Despite the mix-up in the name, I can provide you with information based on Seaford Beach if that would be helpful. Please let me know if you would like me to proceed with this.
