England's most dramatic chalk coast
The East Sussex Heritage Coast runs 14 kilometres between Seaford in the west and Eastbourne in the east. It contains the Seven Sisters National Nature Reserve — designated by King Charles III in March 2026 — and the highest chalk cliffs in Britain at Beachy Head (162 metres). It also contains Birling Gap, Cuckmere Haven, the Cuckmere River estuary, and some of the least-developed coastline in southern England.
The chalk here is 100 million years old. The cliffs are actively eroding — retreating between 30 and 50cm per year — which means the coastline you walk today is measurably different from the one your parents might have walked. The Seven Sisters cliffs will eventually become sea stacks and then disappear entirely. For now, they remain intact, accessible, and exceptional.
This guide covers the full stretch of coast: what's at each location, how to reach it, and how to plan a day that makes the most of it.
Key Locations Along the Coast
Seven Sisters National Nature Reserve
England's most iconic chalk coast — now protected in perpetuity as a National Nature Reserve.
The headline attraction. Seven chalk peaks running 14km between Seaford and Eastbourne. England's most visited National Nature Reserve. The full clifftop walk takes 4–5 hours; shorter sections from Birling Gap take 2–3 hours. Challenging but exceptional.
Explore guideBirling Gap
The most visited access point for the Seven Sisters — arrive before 10am on summer weekends.
Mid-point of the coast, with National Trust café, toilets, and the famous steps down to the beach. The cliff erosion here is visible and rapid — the steps have been replaced multiple times. Good starting point for the Seven Sisters clifftop path in either direction.
Explore guideCuckmere Haven
The best viewpoint for the full Seven Sisters panorama — visible from the valley rather than the clifftop.
The Cuckmere River mouth — one of the few undeveloped river estuaries in southern England. The valley walk from Exceat is flat, easy, and excellent for birdwatching. The beach is accessible only at low tide. Superb views of the Seven Sisters from the valley floor.
Explore guideBeachy Head
Britain's highest chalk cliff and one of the most photographed coastal scenes in England.
162 metres of chalk cliff — the highest in Britain. The red-and-white striped lighthouse sits at the base. A shorter, easier walk than the full Seven Sisters route. The iconic Beachy Head cliff face is better seen from below (boat tours) or from the path above east of Birling Gap.
Explore guideSeaford Head
The quieter approach to Seven Sisters — excellent views and significantly fewer crowds than Birling Gap.
The western gateway. Seaford Head Local Nature Reserve offers excellent walks with fewer crowds than Birling Gap. The views across Cuckmere estuary toward the Seven Sisters are among the best on the coast. Easier parking than Birling Gap on busy days.
Explore guideEastbourne
The main service town for the Heritage Coast — trains, cafés, galleries, and the walk to the cliffs.
The eastern gateway and the nearest town. Victorian seafront, the Pier, the Towner Eastbourne gallery (contemporary art, free entry), and the starting point for the walk west toward Beachy Head and the Seven Sisters. Good facilities and direct trains from London Victoria.
Explore guideWalking Routes
From a 45-minute valley stroll to the full 14km ridge — graded for fitness and time available.
Cuckmere Valley flat walk
Exceat to Cuckmere Haven beach (low tide only). Flat, accessible, excellent for birdwatching and the best ground-level view of the Seven Sisters.
Birling Gap short clifftop
Walk 2–3 Sisters from Birling Gap and return. Good introduction to the clifftop path without full commitment.
Beachy Head to Birling Gap
Walk from Beachy Head eastward, with views of the lighthouse below and the Seven Sisters ahead.
Seaford to Birling Gap
The western section of the Seven Sisters, passing over all seven peaks. Start from Seaford for fewer crowds.
Full Seven Sisters: Seaford to Eastbourne
The complete Heritage Coast walk. 500m total elevation gain. Requires fitness and good footwear. Bus or second car needed at Eastbourne end.
By Train from London
Victoria → Eastbourne: 1h 38min direct, half-hourly. Best for the eastern approach — Beachy Head and Birling Gap.
Victoria → Seaford: 1h 45min (change Lewes). Best for the western approach — quieter paths and the classic Cuckmere view.
Trains run frequently. Off-peak returns are significantly cheaper. On summer weekends, train is strongly recommended over driving — Birling Gap car park fills by 10am.
Parking
Birling Gap: National Trust car park, approximately £5 (free for members). Fills early on summer weekends.
Exceat / Seven Sisters Country Park: East Sussex County Council car park, approximately £4–6. Good for Cuckmere Haven access.
Seaford Head: Free car park on Chyngton Road. Quieter than Birling Gap. Good starting point for walks.
Eastbourne seafront: Multiple pay-and-display options. Good for bus connection to Beachy Head.
