South Downs Way in West Sussex

Practical Planning for the South Downs Way in West Sussex

The South Downs Way is a 160 km (100 mile) National Trail, according to the South Downs National Park Authority. The West Sussex section runs 83 km (52 miles) from Bury Gate near the A29 to Ditchling Beacon near the A23. This page gives the decision rules, terrain details, and transport logistics for each section so you can plan a day walk, not an expedition.

The Core Decision Rule: Section by Terrain and Transport

Break the West Sussex section into four segments. Each segment has a distinct surface, gradient, public transport access, and weather exposure. Use the table below to match a section to your group’s ability and available time.

Walking times are based on the official South Downs National Park Authority estimates for an average adult walking 5 km/h on flat ground. Real-world times for families with children are often 20-30% longer due to stops, photo breaks, and uneven surfaces (VisitBritain guidance).

How to Choose Your Section

For a half-day with a train return (Section 1): Start at Bury Gate car park (limited spaces) or take the Compass Travel 100 bus from Arundel to Bury. Walk 16 km to Amberley Mount, then descend to Amberley railway station. The Southern line runs hourly on weekdays. Check National Rail for Sunday frequencies, which can reduce to every two hours. The surface is chalk downland and river valley paths, with minimal steep sections. Carry water; there are no reliable taps on this section (South Downs National Park Authority).

For a full day with a car (Section 2): Park at Truleigh Hill (limited, no overflow) or at the South Downs Centre in Midhurst and take a taxi to the start. This section has the most elevation gain, with steep climbs on the escarpment. The surface is chalk, which becomes slippery and sticky after rain (Met Office: average annual rainfall 800 mm). Do not attempt this section in wet conditions unless you have walking poles and boots. The nearest hospital for the west half is St Richard’s Hospital, Chichester; for the east half, Royal Sussex County Hospital, Brighton. Mobile reception is variable; carry a paper map (OS Explorer OL11).

For a short, exposed ridge walk (Section 3): Park at Ditchling Beacon car park (pay & display, often full by 10am on sunny weekends). Walk west toward Truleigh Hill or east toward the A23. The ridge is exposed to wind; average summer temperature is 18°C but wind chill can be significant (Met Office). This section is not suitable for pushchairs due to narrow, uneven paths and occasional stiles (South Downs National Park Authority). Dogs are allowed on lead near livestock; the South Downs National Park Authority advises keeping dogs under close control year-round.

For a linear walk with a bus return (Section 4): Take the Brighton & Hove 77 bus from Brighton to Ditchling. Walk the 23 km to the East Sussex border, then return by bus from a stop near the A23. The bus service is hourly on weekdays; check for Sunday cancellations. This section includes a steep descent to the A23, then rolling downland. Allow 6-7 hours of walking time.

Chichester

Chichester is the western gateway to the South Downs Way. From Chichester, take the Stagecoach 1 bus to Midhurst (hourly on weekdays), then connect to the trail at Bury Gate or Amberley. The South Downs Centre in Midhurst (run by the South Downs National Park Authority) has maps, toilet facilities, and staff who can advise on current path conditions. Chichester Harbour, an AONB, is a separate destination; the South Downs Way does not pass through it.

Arundel

Arundel is the nearest town to Section 1. The trail passes 2 km from the town centre. Arundel railway station is on the Southern line (hourly to London Victoria). The Arundel Wetland Centre (WWT) and Arundel Castle are separate attractions. For the South Downs Way, use the car park at Amberley (pay & display) or the limited parking at Bury Gate. The Compass Travel 100 bus connects Arundel to Worthing via the trail.

Worthing

Worthing is the nearest coastal town to the South Downs Way, but the trail does not reach the coast. From Worthing, take the Compass Travel 100 bus to Arundel or the Stagecoach 1 to Midhurst. Worthing Pier is a separate seaside attraction. The South Downs Way is a downland trail; do not confuse it with the coastal path.

Crawley

Crawley is north of the South Downs, in the Weald. The South Downs Way does not pass through Crawley. To access the trail from Crawley, drive to Ditchling Beacon (30 minutes via A23) or take a train from Three Bridges to Hassocks (Southern line, hourly on weekdays). The A23 is the main road artery; allow extra time for congestion on sunny weekends.

Horsham

Horsham is north-west of the South Downs. From Horsham, drive to Amberley or Truleigh Hill (25-35 minutes). The A24 is the main route. Horsham railway station has Southern trains to London Victoria and to Amberley (change at Barnham). The South Downs Way does not pass through Horsham; it is a start point for car access.

Weather and Safety Checklist

• Check the Met Office forecast for the specific section before travel. Wind exposure is high on open downland (South Downs National Park Authority).
• Carry a paper map (OS Explorer OL11). Mobile reception is variable, especially in the Weald (West Sussex County Council).
• Carry at least 1 litre of water per person. There are no reliable water sources on the trail (South Downs National Park Authority).
• Check tide times if walking near the River Arun crossing (Section 1). The river is tidal; the path may be cut off at high tide (Environment Agency).
• Plan to finish before dusk. There is no lighting on the trail (South Downs National Park Authority).
• Keep dogs on a lead near livestock. Livestock grazing is common on the downland (South Downs National Park Authority).
• Check National Rail for engineering works on weekends. Sunday services are often reduced to every two hours and may be replaced by buses.
