Why walk a line, not a loop?

Britain's coast rarely obliges with a convenient circuit. Estuaries, cliffs and long beaches tend to run in one direction, which means a there-and-back walk often ends up repeating the best bits with tired legs. A linear route lets you keep moving, one stretch of coast at a time, finishing somewhere new with a pint and a bus stop rather than a trudge back to the car.

The catch, of course, is the car. Parking at one end and walking away from it is the classic obstacle to coastal walking. But it is a much smaller obstacle than most people assume. Buses, trains and ferries between coastal towns are often surprisingly good, and using them turns a logistical headache into one of the nicest parts of the day.

Start with the timetable, not the map

The most useful habit I can pass on is this: plan the journey home before you plan the walk. Open the timetable first, note the last sensible departure, then work backwards to your start point and build a route that fits between them.

A few things are worth checking every single time:

• Last departure, not first. It is easy to find a morning bus and much harder to find one at half past six in the evening.
• Seasonal services. Many coastal buses only run from Easter or late May until September, and rural routes often thin out or vanish entirely in winter.
• Day of the week. Sunday services disappear first, and some routes run on market days only.
• School terms. A bus that runs three times a day in term time may run twice in the holidays, or the reverse.
• Request stops. On some rural routes and a good few coastal railway halts, you must signal clearly or the bus or train will sail past.

Write the times down on paper. Phone batteries die on clifftops, and signal is patchy exactly where you need it most.

Railways that hug the shore

Britain has a fine tradition of trains running absurdly close to the sea, and these lines are the backbone of a linear coastal walking trip. Stations often sit within a few minutes of the path, which means you can hop off, walk a satisfying ten or twelve miles, and pick up a train at the other end without ever touching a road.

Where a line runs along the coast, it usually links a string of small stations that make excellent start and finish points. Look for the request-stop halts: they are frequently the closest to the path, though you will need to tell the guard you want to get off, and stand somewhere visible if you are waiting.

Rail also solves the awkward problem of estuaries. A river mouth that would add fifteen miles of inland detour on foot is often a ten-minute train ride, sometimes with a viaduct view worth the fare on its own.

Buses, ferries and the small crossings

Coastal buses are the unsung heroes of this kind of day out. They reach villages the railway never touched, and many run along the coast road with sea views to match anything on the walk. If a route only runs twice a day, treat it as a fixed point and shape everything else around it.

Ferries are the real treat. Foot-passenger crossings over estuaries, harbour ferries and seasonal summer services can link two stretches of coast that look impossibly far apart on a map. They also turn a long road-bound slog into a short, breezy hop with seals for company.

Ferries come with their own rules, though, so check before you commit:

• Some run only at high water, or only between certain states of the tide.
• Several are weather-dependent and cancel in a stiff wind.
• A few take cash only, or need booking a day ahead for foot passengers.
• Winter timetables can be a fraction of the summer ones.

The tide, the weather and the last bus

Two clocks run at once on a coastal walk: the tide and the timetable. A section that is passable at low water in June may be a wade in October, and a route that fits comfortably between buses in midsummer can leave you walking in the dark by Bonfire Night. Check the tide tables for the middle of your walk, not just the start, and check sunset as carefully as you check the last bus.

Always have a fallback. Know where the nearest accommodation is, keep a taxi number saved offline, and accept that a missed connection might mean a long wait in a pub rather than a disaster. That is not a failure of planning; it is part of the day.

Tickets, kit and small kindnesses

Buy your return or day ticket before you set off where you can, and consider rail add-on bus tickets, rover tickets and family fares — they can cost far less than singles bought on the day. Contactless is now common on town routes but not guaranteed in the countryside, so carry a little cash as backup.

Pack light, because you are carrying everything up a hill and onto a bus. Poles, a waterproof that actually works, water, and a printed timetable cover most eventualities. If you are unsure where to get off, tell the driver your destination when you board: on rural routes they will usually call it out, and often drop you nearer the path than the official stop. It is one of the quiet pleasures of travelling this way — the coast, a timetable, and a stranger who knows exactly where you mean.
