A Slow Travel Guide to Britain's Coastal Railway Lines

The case for going car-free by the coast

Britain's coastline is a patchwork of cliffs, estuaries, saltmarsh and shingle, and much of it is best reached by rail. Branch lines thread through landscapes that roads simply cannot follow — along sea walls, beneath wooded valleys, past tidal creeks where herons stand. Arriving by train also means you sidestep the summer scrum for a parking space in a harbour town, and you see the coast as it was meant to be seen: slowly, through a window that opens onto the sea.

There is a conservation argument, too. Coastal habitats are among the most fragile in the UK, and compact seaside towns, narrow lanes and eroding cliff paths cope badly with heavy traffic. Travelling by rail and walking or cycling the last mile keeps your footprint lighter, and leaves the places you love much as you found them.

Lines worth planning a trip around

A handful of coastal routes reward the journey in its own right, not merely as a way of getting somewhere.

• St Ives Bay, Cornwall. A short hop from the main line at St Erth, with the final minutes running alongside the dunes at Hayle. Sit on the seaward side for the sweep into St Ives harbour.
• The Cambrian Coast, west Wales. An unhurried run beside the Dyfi, the Mawddach and Cardigan Bay, past Barmouth's timber viaduct and the dunes at Harlech. Tides here move quickly — check tables before planning a beach walk.
• The Cumbrian Coast. Right along the Irish Sea edge, past the long shingle of the Ravenglass estuary, with fine cliff walking between St Bees and Whitehaven.
• The Esk Valley, North Yorkshire. From Middlesbrough up through the moors to Whitby, linking heather moorland with the harbour, the abbey steps and a very good fish supper.
• The West Highland route to Mallaig. Not strictly a branch, but the Glenfinnan viaduct, the Sound of Arisaig and the Small Isles beyond Mallaig make it one of the great coastal journeys.

Practical notes for a branch-line day

Branch lines run infrequently, so a little planning goes a long way. Check the first and last trains before you commit to a walk, and build in a buffer — a missed connection on a Sunday can mean a long wait on a windswept platform.

• Tides come first. Many of the best walks cross sand, causeways or estuary paths that flood. Carry a printed tide table; phone signal is patchy on cliff stretches.
• Weather changes fast. Coastal fog and sea fret can arrive within the hour. Pack a waterproof and a warm layer, even in July.
• Travel midweek or out of season. You will find quieter carriages, easier tables and a warmer welcome in cafés that are rushed off their feet in August.
• Bikes need booking. Most coastal services carry only a handful of cycles, and reservations are essential in summer.
• Pack light. A single rucksack is far easier on a crowded platform than a wheeled case, and many guesthouses will hold bags before check-in.

Staying, eating and exploring without a car

The trick is to choose a base within walking distance of a station and stay put for a few days. Harbour towns such as Whitby, Barmouth, St Ives and Mallaig all work well: you can step off the train, drop your bag, and spend the rest of the week on foot.

Eat where the boats land. Harbour-side cafés, pub kitchens and fishmongers in these towns tend to source locally, which cuts food miles and keeps money in the coastal economy. Ask what came in that morning — the answer is usually the best thing on the menu.

For longer days out, look for waymarked coast paths that loop back to the station, or use a local bus to extend your range without adding a car to the equation. Many seaside towns also have bike hire within a few minutes of the platform.

Treading lightly on a fragile coastline

Coastal conservation is not about staying away — it is about visiting well. Stick to marked paths on cliff tops and dunes, where fragile plants and nesting birds are easily crushed. Keep dogs on leads around seabird colonies and on beaches where seals haul out, and give wildlife a wide berth: a disturbed seal pup or a flushed oystercatcher nest is a real cost.

Take litter home, including the small stuff. Fishing line, balloon fragments and plastic bottle tops do enormous damage to seabirds and marine life. If you find a stranded animal or an injured bird, report it to a local wildlife trust rather than intervening yourself.

Finally, spend locally and travel gently. Buying a coffee, a night's bed and a bag of chips in a seaside town is one of the most effective things a visitor can do to keep that community — and the coast around it — thriving.
