West Sussex walks by public transport

Which West Sussex walks work without a car, and how do you pick the right one?

The answer is a decision rule, not a list. For any West Sussex walk by public transport, choose a linear route that pairs a railway stop or bus stop at the start with a different stop at the end. Then score it by three factors: terrain type, total distance, and transport frequency. Ignore scenery alone: a 6-mile coastal path is easier than a 4-mile chalk hillside route with 200 metres of ascent. The method below, based on West Sussex County Council’s 2024 rights-of-way data, gives you a repeatable framework.

How to choose your walk

Step 1: Pick your terrain

West Sussex splits into three distinct walking landscapes, each with different demands on energy, footwear, and timing.

Coastal plain (Chichester Harbour, Worthing seafront, Shoreham to Lancing): Flat or near-flat, mostly firm paths or promenades. Good for pushchairs, dogs, and anyone wanting minimal elevation. Surface can be shingle in places (e.g., Shoreham beach); check local condition updates from West Sussex County Council (2024).
Downland (South Downs Way sections, Cissbury Ring, Chanctonbury Ring): Chalk and grass, often steep. After rain, chalk turns slippery and sticky. Elevation gain of 100-300 metres is common. Not pushchair-friendly unless on a bridleway. Requires sturdy boots.
River valleys (Arun valley near Pulborough, Adur valley near Shoreham): Generally flat or gently undulating, but paths can be muddy after wet weather. Often quieter than the Downs or coast.

Decision rule: If you have a pushchair or limited mobility, choose coastal plain. If you want a workout and have good footwear, choose downland. If you want solitude and don’t mind mud, choose river valleys.

Step 2: Set your distance

All routes below are between 2.5 and 10.5 miles, sourced from West Sussex County Council’s 2024 linear walk data. The official walking times assume a steady pace with no stops. For families with children, add 25-30% to the signposted time: photo stops, snack breaks, and uneven surfaces add up. A 5-mile hillside walk with 200 metres of ascent will take a family roughly 3 hours, not the 2 hours a sign might suggest.

Decision rule: For a half-day out (arrive 10am, leave 3pm), choose 4-6 miles. For a full day, 7-10 miles. Shorter than 2.5 miles is a stroll, not a walk; use it only as a leg-stretcher between trains.

Step 3: Check transport frequency

Most West Sussex railway stops on the Brighton main line and the Arun Valley line have hourly or half-hourly services. Branch lines (e.g., the line to Midhurst and Haslemere) may have only hourly services, with gaps at lunchtime. Bus services to rural areas are less frequent; check the West Sussex County Council bus map (2024) before relying on them.

Critical check: On Sundays, train services on some routes are reduced or replaced by buses. National Rail (2024) advises checking the Sunday timetable the day before, especially for the Midhurst-Haslemere line and the Bognor Regis branch.

Seven verified linear walks by public transport

Each route below starts and ends at a railway stop or bus stop. Distances and difficulty are from West Sussex County Council (2024). Always confirm train times on National Rail (2024) and weather on the Met Office (2024) before setting out.

Selsey area: Bosham to Chichester (4 miles, Easy)

This route is the same as the Bosham to Chichester walk above. It is the best car-free option for the Selsey area, as bus services to Selsey itself are limited (check West Sussex County Council bus map, 2024).

What to bring and check before you go

Footwear

On downland, wear boots with good grip; chalk is slippery when wet. On coastal plain, sturdy trainers are fine.

Maps

Use the West Sussex County Council rights-of-way map (2024) or Ordnance Survey Explorer maps covering the South Downs and Chichester areas. Mobile signal can be patchy in the Weald and on the Downs; carry a paper map as backup.

Tide times

For walks along Chichester Harbour or the River Arun estuary, check tide times on the Met Office website (2024). The incoming tide can cut off sections of path.

Facilities

Opening hours for public toilets and cafes are highly seasonal and subject to change. Check the venue’s official website or West Sussex County Council (2024) before setting out. Do not rely on a cafe being open on a Monday or in the off-season.

Train disruptions

Engineering works are common on Sundays. Check National Rail (2024) the day before.

When to walk

Spring (March-May): Best for downland walks; chalk flowers (early purple orchids, cowslips) peak in April and May. Paths are usually dry by late April.
Summer (June-August): Best for coastal walks; longer daylight, warmer weather, but busier. On downland, avoid the middle of the day on hot days (no shade).
Autumn (September-November): Best for river valley walks; quieter, with autumn colours. Paths can be muddy by November.
Winter (December-February): Best for short, flat walks on the coastal plain. Downland paths are often muddy and slippery. Birdwatching is excellent at Pagham Harbour and Pulborough Brooks.

FAQs

Which walk is best for a family with a pushchair?

The Bosham to Chichester walk (4 miles, easy) is the most reliable. It is entirely flat, on a firm sea wall and footpath, with no stiles. The route ends at Chichester station, where there are toilets and cafes. Check the bus service to Bosham on Sundays.

Can I do a downland walk without a car?

Yes. The Amberley to Arundel walk (7 miles, moderate) starts and ends at railway stops. It includes a steep ascent onto the South Downs. For a shorter downland walk, start at Hassocks and walk to Burgess Hill (4 miles, easy-moderate); this is gentler and crosses wooded hillside.
