The Best Walks in the South Downs
Chalk downland from Winchester to Eastbourne, ending in the most photographed cliffs in England. It is the newest national park and, on our data, the one with more sites inside its boundary than any other, 26 of them.
Published 19 August 2026
The South Downs became a national park in 2010, the most recent in England, and it is unlike the others in a specific way: it is a lived-in, farmed, thoroughly populated landscape rather than a wilderness. That is exactly why it works for walking. Villages every few miles, pubs in most of them, railway stations along both flanks, and a chalk ridge running the length of it with views to the sea.
The Seven Sisters
The best-known walk in the park and one of the best coastal walks in England: a switchback of chalk cliffs between Cuckmere Haven and Birling Gap, then on to Beachy Head. The classic route runs from Seven Sisters Country Park at Exceat to Birling Gap, about 5 miles one way, with a bus back.
It is relentlessly undulating rather than steep, and the sequence of climbs is what tires people. There is no shelter, no water and no shortcut once you commit.
The rest of the classics
| Walk | Roughly | What you get |
|---|---|---|
| Seven Sisters, Exceat to Birling Gap | 5 miles | The cliffs, Cuckmere meanders, a bus back |
| Devil’s Dyke circular | 4 miles | The deepest dry valley in Britain, above Brighton |
| Ditchling Beacon from Lewes | 7 miles | One of the highest points on the Downs, with a huge view north |
| Old Winchester Hill | 3 miles | Iron Age hillfort, chalk grassland, orchids in June |
| Cissbury Ring | 3 miles | Neolithic flint mines and a vast hillfort above Worthing |
| Arundel and the park | 6 miles | Castle, wetland centre and downland in one loop |
The South Downs Way
The National Trail runs 100 miles from Winchester to Eastbourne along the chalk ridge, and it is the only National Trail that is entirely bridleway, walkable, rideable and cyclable end to end. That makes it unusually popular with mountain bikers and one of the few long trails where you can do the whole thing on a horse.
- 8–9 days walking, or 2–3 days on a bike.
- West to east is standard, finishing at Beachy Head above Eastbourne.
- Water is the constraint. Chalk drains, so there are no streams on the ridge. You fill up in villages, which often means dropping off the top and climbing back.
Getting there by train
This is the South Downs’ quiet advantage. The London–Brighton and coastal lines put stations at Amberley, Lewes, Southease, Berwick, Hassocks and Eastbourne, all within reach of the ridge. Very few national parks let you walk a linear route and take a train back from the far end.
When to go
June for the chalk grassland: this is some of the richest wildflower habitat in Britain, with orchids and a butterfly list that includes the Adonis blue and the chalkhill blue. Autumn for the light and empty paths. Winter is walkable but chalk and clay turn greasy, and the Downs get more wind than their modest height suggests.
Where to stay
We list 35 sites across the South Downs catchment, 26 of which sit inside the national park boundary, the highest of any UK park on our data, as covered in every glamping site inside a national park.

Common questions
- What is the best walk in the South Downs?
- The Seven Sisters from Exceat to Birling Gap, about five miles of chalk cliffs with a bus back. Devil’s Dyke and Ditchling Beacon are the best inland options.
- How long is the South Downs Way?
- 100 miles from Winchester to Eastbourne. It is the only National Trail that is bridleway for its entire length, so it can be walked, cycled or ridden.
- Can you walk the South Downs by train?
- Unusually well, yes. Amberley, Lewes, Southease, Berwick, Hassocks and Eastbourne all sit within reach of the ridge, which makes linear day walks straightforward.
- Are the Seven Sisters cliffs dangerous?
- Yes. The chalk is actively eroding, falls are frequent and the ground overhangs the edge where you cannot see it. Stay well back and keep dogs on leads.
