Seven Sisters & Cuckmere Haven: The Complete Visitor Guide
The Seven Sisters chalk cliffs and Cuckmere Haven are Seaford's most famous natural landmarks. Here's everything you need to know — walks, wildlife, getting there, and where to eat afterwards.
The Seven Sisters
The Seven Sisters are a series of chalk sea cliffs forming part of the South Downs between Seaford and Eastbourne. In March 2026, the area was formally declared as England's newest National Nature Reserve, covering 1,500 hectares.
The classic view — the undulating white cliffs stretching into the distance — is one of the most photographed landscapes in England. The best viewpoint is from Seaford Head, looking east along the coastline.
Cuckmere Haven
At the western end of the Seven Sisters, the River Cuckmere winds through its floodplain to meet the sea at Cuckmere Haven. The meandering river, chalk grassland, and shingle beach create a landscape that's barely changed in centuries. The area is managed jointly by the South Downs National Park Authority, National Trust, Sussex Wildlife Trust, and Natural England.
Walking Routes
The Classic Walk (7 miles one-way): From Exceat (Seven Sisters Country Park visitor centre) east along the cliff tops over all seven peaks to Birling Gap. Strenuous but spectacular. Return by bus (Route 12/12X) or arrange transport.
Cuckmere Haven Circuit (3 miles): From Exceat, follow the river south to the beach, return via the cliff path. Moderate, family-friendly.
Seaford Head to Seven Sisters (4 miles): Start at Seaford seafront, cross Seaford Head, descend to the river mouth and Cuckmere Haven. Moderate to strenuous.
Wildlife
The NNR supports chalkhill blue butterflies, yellowhammers, skylarks, bee orchids, and peregrine falcons. Cuckmere Haven attracts wading birds, and the river is home to kingfishers.

Practical Tips
- Check the Seven Sisters website for live access alerts — Hope Gap and Birling Gap paths occasionally close due to cliff falls

- Dogs welcome but on leads through livestock areas
- The cliffs are unfenced and actively eroding — stay well back from edges
