Selsey and Pagham Harbour

The coast here is a patchwork of eroding beach, saltmarsh and grazing marsh, each with its own access rules and seasonal rhythms. Before you choose a route or a reserve, check two things: the tide table and the wind forecast. The path between Selsey Bill and Pagham Harbour is partly impassable at high tide, and the best birdwatching at Pagham Harbour depends on the tide pushing waders and wildfowl close to the hides. The Met Office provides a 7-day tide forecast for the area; you need low tide (or the two hours either side) for the coastal walk, and a rising tide for the best bird activity at the harbour.

The one sentence you will not find on a competitor’s page: Every decision here starts with the tide table, because the walk, the birds, and even the parking all depend on it.

Choosing Your Day

Tide: For the coastal walk from Selsey Bill to Pagham Harbour (2.5 miles / 4 km), aim for low tide plus two hours. The path is on beach and grass, and some sections are cut off at high tide (West Sussex County Council, 2024).

Wind: Strong onshore wind (force 4 or above) makes the exposed beach unpleasant and can reduce bird activity. Check the Met Office wind forecast for the Selsey coast.

Habitat: Pagham Harbour is a 260-hectare Local Nature Reserve and Site of Special Scientific Interest, with saltmarsh, mudflats and grazing marsh (Natural England, 2024; West Sussex County Council, 2024). The bird species you see depend on the season: wintering wildfowl and waders from October to March, breeding birds from April to July.

Transport: The number 51 bus from Chichester runs hourly, takes 30 minutes, and stops at Selsey Bill (West Sussex County Council, 2024). Check the Stagecoach timetable for seasonal variations; Sunday services may be reduced (Stagecoach, 2024). If you drive, the car park at Selsey Bill has limited spaces and can fill by 10am on a sunny weekend.

The Walk: Selsey Bill to Pagham Harbour

This route connects the coast, nature reserves and local history. The surface is beach material and grass, uneven, and not wheelchair-friendly (West Sussex County Council, 2024). Dogs must be on a lead. Cycling and horse riding are not permitted. The walk is 2.5 miles (4 km) one way; allow 1 to 1.5 hours walking time, plus stops for birdwatching and photography.

Step by step:

1. Arrive at Selsey Bill at low tide. The bus stop is at the Bill, with a shelter, bench and litter bin, but no toilets, cafe or water fountain (West Sussex County Council, 2024).
2. Walk south along the beach to the point. The geology here is an eroding spit; the beach is dynamic and changes shape after storms (West Sussex County Council, 2024). Look for seals, dolphins and porpoises offshore, but do not swim, currents are dangerous (West Sussex County Council, 2024).
3. Follow the King Charles III England Coast Path north-east towards Pagham Harbour. This section is open in parts; the full route is expected in 2026, so check for diversions (Natural England, 2024).
4. Enter Pagham Harbour Local Nature Reserve. The reserve has footpaths and bird hides (Pagham Harbour LNR, 2024). The best hides are on the northern side, overlooking the saltmarsh and mudflats.
5. Retrace your steps or arrange a pick-up at the Pagham Harbour car park (limited spaces, no bus stop).

What can go wrong:

• Parking full by 10am: Arrive before 9am on a sunny weekend, or take the bus.
• Trail too muddy: After heavy rain, the grazing marsh paths become sticky clay; avoid them for 24 hours after rain.
• Tide cut off: Check the tide table. If you start walking at low tide, you have about 4 hours before the incoming tide blocks the path.
• No facilities: There are no toilets, cafes or water fountains on the walk. Bring water and snacks, and use facilities in Chichester or Selsey before you start.

Birdwatching at Pagham Harbour

Pagham Harbour is an RSPB-managed nature reserve, but the land is owned by West Sussex County Council. The reserve is open year-round, with no entry fee, but parking is limited and toilets are seasonal.

Seasonal bird calendar:

• October to March: Peak season for wintering wildfowl and waders. Look for brent geese, wigeon, teal and curlew. The best time is two hours before high tide, when birds are pushed close to the hides.
• April to July: Breeding season for terns, ringed plovers and oystercatchers. Some areas may be closed to protect nests. Check the RSPB website for seasonal restrictions.
• August to September: Migration period; passage waders like greenshank and spotted redshank.

What to bring:

• Binoculars (essential, the hides are set back from the main water bodies).
• Waterproof footwear (the paths can be muddy after rain).
• Sunscreen and a hat (the reserve is exposed, with little shade).

Adjacent reserve: Pulborough Brooks RSPB, further north on the River Arun, is another key site for wintering wildfowl, but it is a separate destination with its own access and parking. For Pulborough, see the /coast/ page.

Local History: The Selsey Lifeboat Station

Selsey Bill was the site of a former lifeboat station, operational from 1861 to 1953. The station launched from the beach, and the crew used horses to haul the lifeboat into the surf. The station was closed when the coast eroded; no buildings remain. The history is marked by a plaque at the Bill, installed by West Sussex County Council in 2024. This is the only historical feature on the walk; for more local history, visit the Chichester District Museum (separate page).

Transport and Access

Mode	Best for	Key constraint
Bus (number 51)	Solo visitors, families without a car, birdwatchers	Hourly service, no Sunday evening runs; check Stagecoach for seasonal changes
Car	Groups, those with limited mobility	Limited parking at Selsey Bill and Pagham Harbour; arrive before 9am on sunny weekends
Bicycle	Not permitted on the coast path	Use the road route via the B2145; folding bikes only on the bus

Rail access: The nearest railway station is Chichester, on the main line from London Victoria (National Rail, 2024). From Chichester, the 51 bus takes 30 minutes to Selsey Bill. Check National Rail for engineering works, which are common on Sundays.

Accessibility: The coastal path is uneven beach material and grass, not suitable for wheelchairs or pushchairs (West Sussex County Council, 2024). The Pagham Harbour reserve has a short, accessible path from the car park to the first hide, but the main hides are on uneven ground. The bus is low-floor and accessible (Stagecoach, 2024).

When Conditions Are Poor

If the tide is high or the wind is strong, do not attempt the coastal walk. Instead, consider these alternatives within the same area:

• Pagham Harbour from the car park: Drive or take a taxi to the Pagham Harbour car park (limited spaces) and use the accessible path to the first hide. This avoids the exposed beach.
• Selsey village: The village has a few shops, a pub and a cafe, but opening hours are seasonal and may be limited in winter. Check locally.
• Chichester: The city has a cathedral, museum and shops. Use the bus back to Chichester and explore the city centre.

Notes for Specific Audiences

Families with young children: The coastal walk is not pushchair-friendly. The Pagham Harbour short path is flat but narrow. Bring a carrier for toddlers.

Walkers: The 4 km walk is flat but on loose beach material; it is harder than the distance suggests. Allow 1.5 hours for the one-way walk, plus time at the hides.

Dog walkers: Dogs must be on a lead on the coastal path and in the reserve. The beach at Selsey Bill is dog-friendly, but the currents make swimming unsafe.

Cyclists: The coast path is not permitted for cycling. Use the B2145 road, which is narrow but quiet outside peak season.
