Planning a Long Distance Walk Along the South Downs Way

Why the South Downs Way rewards a little planning

The South Downs Way runs for roughly 100 miles (160 km) between Winchester and Eastbourne, following the crest of the chalk downs across Hampshire and Sussex. It is one of the gentlest National Trails in Britain — no scrambling, no navigation nightmares — but that reputation can lull people into under-preparing. The climbing is relentless rather than dramatic: add it all up and you will haul yourself up something close to 4,000 metres over the full route.

The other quirk is that almost the entire trail is bridleway. You will be walking on wide, firm chalk tracks shared with horse riders and mountain bikers, which makes for fast going in dry weather and greasy, slippery going after rain. Plan the days, and this becomes one of the most enjoyable long walks in the country.

Choose a direction and be honest about daily mileage

Most people walk west to east, from Winchester to Eastbourne, so the prevailing wind and the sun are behind them. It also puts the hardest section — the rollercoaster of the Seven Sisters and Beachy Head — at the end, when you are fittest. Walking east to west has its own appeal: you finish in a cathedral city with decent trains and a proper celebratory pint.

Eight to ten days is the realistic window for most walkers. A comfortable rhythm looks like this:

• Winchester to Exton or Meonstoke — a gentle opener, about 12 miles
• Meonstoke to South Harting — the big day over Butser Hill and Harting Down, 14–15 miles
• South Harting to Amberley — long, rolling, and short of water, 15 miles
• Amberley to Steyning or Upper Beeding — 12–13 miles
• Steyning to Lewes — the classic day over Devil's Dyke and Ditchling Beacon, 14 miles
• Lewes to Alfriston — shorter, but the climbs start to bite
• Alfriston to Eastbourne — only 12 miles, and the toughest of the lot

If you have less time, cut the western half rather than the east. It is prettier than people expect, but the eastern section is the one you will remember.

Book your beds before you book anything else

Accommodation is the single biggest constraint on this route. The trail runs along a ridge, and most villages sit a mile or two below it, so your overnight options are limited to a handful of pubs, farm B&Bs, bunkhouses and small hotels in places like Exton, East Meon, South Harting, Cocking, Amberley, Steyning, Lewes and Alfriston.

Summer weekends in Amberley, Alfriston and Lewes can fill six months ahead. Book the whole chain of nights in one sitting, before you commit to dates, and be prepared to walk a mile or two off-route to reach a bed. A few small operators will move a bag between stops if booked well ahead, which turns a slog into something genuinely pleasurable.

Wild camping is not permitted along most of the route without the landowner's permission. There are a handful of farm campsites and a couple of hostels and bunkhouses, but they are spread thinly, so treat camping as a logistical puzzle rather than a fallback.

Water, food and the shape of a day

The chalk ridge is dry. Streams are rare, taps are rarer, and the villages with shops are mostly down in the valleys. Carry at least two litres and refill whenever you pass a village, a pub or a churchyard tap. In hot weather this is the thing that catches people out.

• Shops: Winchester, Petersfield area, Storrington, Steyning, Lewes, Alfriston — plan your food around these
• Pubs: often a mile or more off the ridge, and often closed on Mondays and Tuesdays
• Water: take it when you see it, not when you need it

A good day's rhythm is an early start, a long middle stretch with a packed lunch on a trig point, and an arrival at your bed by late afternoon. There is very little shade on the downs, so the middle of a July day is best spent eating, not climbing.

Weather, ground and what to carry

Chalk is wonderful in dry weather and treacherous in the wet. After heavy rain the tracks polish up like ice, especially on the descents into Amberley and the Cuckmere valley. Grippy soles matter more than boots that look the part.

Exposure is the other consideration. The ridge is open, so wind and sun both hit harder than the modest heights suggest. A light windproof, a hat, and sun cream earn their place in the pack from March onwards. Navigation is straightforward — the route is waymarked with the acorn symbol — but a 1:25,000 paper map is still worth carrying, particularly where the trail crosses farmland and the waymarks thin out.

Getting to the start and home from the finish

Winchester has fast trains from London, and Eastbourne is on the mainline back to Victoria via Lewes and Brighton. Both ends are easy without a car, which is one of the quiet joys of this route. If you are breaking the walk into sections, Petersfield, Amberley, Hassocks, Lewes and Southend all sit close enough to the trail to serve as weekend start and finish points, with buses filling the gaps where the railway does not reach.

Book your train home for late afternoon on your final day, not mid-morning. The last stretch over the Seven Sisters has a habit of taking longer than the map suggests, and you will want time at Beachy Head to sit down and enjoy what you have just done.
