Seven Sisters Coastal Walk

The Seven Sisters Coastal Walk starts at Seaford station, reached from London Victoria in around 1 hour 20 minutes with a change at Lewes, 85km south of London; no permit is required to walk the South Downs Way section covered here. The 14km route is challenging, with multiple steep climbs over seven chalk headlands each roughly 75 to 100m high, giving significant cumulative elevation gain despite the modest overall distance, and classing the walk as hard. The surface is grass and chalk clifftop path, fully exposed to wind and sun with no shade anywhere along the route. Key landmarks include the Cuckmere Valley's meandering river near the start, the seven named chalk headlands themselves, and Birling Gap, roughly 9km in, which has a café, toilets, and a bus stop that serves as a natural point to shorten the walk. There are no facilities between Seaford and Birling Gap, so walkers should carry all water and food needed for the middle section. The walk finishes in Eastbourne, with direct rail service back to London Victoria in about 1 hour 30 minutes. No shelter exists along the exposed clifftop, and the chalk cliffs are actively eroding and unfenced in most places, so walkers must stay well back from the edge at all times. Most walkers complete the full route in five to six hours, encountering some of the most dramatic white chalk cliff scenery in southeast England along the way.
