Planning a Safe Circular Walk Along the Coastal Path

Why a circular coastal walk needs more planning than an inland loop

Coastal walking is some of the best walking Britain has to offer, and a circular route is the most satisfying way to do it: out along the cliff tops, back along the shore, ending where you left the car. But the coast is a restless neighbour. Cliffs erode, paths slip, estuaries fill and empty twice a day, and the shortcut you can see on the map is often a mile-wide inlet with no bridge. Inland, if a path is blocked you can usually reroute across a field. On the coast, you often cannot.

That is why a circular coastal walk deserves twenty minutes of planning before you pull your boots on. None of it is complicated, and most of it is enjoyable — reading a tide table, tracing a headland on a map, working out where you will stop for lunch. Here is how to do it properly.

Read the tide times before you read anything else

Tides are the single biggest factor in coastal safety, and the one people most often get wrong. Tide times vary around the coast: a high water at one harbour may be an hour or more different from the next bay along. Always use the predictions for the nearest standard port, then adjust for local quirks. Tidal range around much of the UK runs to four or five metres, which means a wide expanse of sand can become deep water surprisingly fast. Tides are also not symmetrical — the flood can move across flat sand at walking pace or faster, and it approaches from behind you as often as in front.

• Note the time and height of high water, and whether it is a spring or neap tide. Springs push much further up the beach.
• Plan any beach or causeway section to be completed at least two hours before high water, and ideally on a falling tide.
• Mark escape routes on your map: steps, slipways, ramps and paths leading up from the shore. Know where the nearest one is at all times.
• Never walk out onto sandbanks or around headlands cut off by the tide, however inviting the sand looks.

Carry a map you can actually navigate with

A 1:25,000 scale map is the right tool for coastal paths, where the difference between a path and a crumbling edge can be a few metres. Phone mapping is useful as a backup, but batteries die, screens are unreadable in bright sun, and signal vanishes in coves and under cliffs. Paper does not.

• Write down the key grid references for your start point, your planned lunch stop and any escape points.
• Learn the six-figure grid reference for where you parked. It is the quickest way to tell someone where you are in an emergency.
• Take a compass and know how to take a bearing. Sea fog and sudden mist on a headland can erase the view in minutes.
• Check for temporary path diversions, landslips and closed sections before you go, and respect any notices you find on the day.

Tell someone your route — and agree a trigger time

"I'm going for a walk" is not a plan. Leave a route card with someone reliable: where you are starting, the car park or street name, your intended route in outline, and the time you expect to be back. Then agree what happens if you are not.

• Give a latest-return time and a clear instruction to raise the alarm if you have not called by then.
• Send a message when you finish. This is the most important part of the whole arrangement.
• If you change your route mid-walk, tell someone if you can. If you cannot, stick to the plan you left.
• Walking alone is fine, but the route card matters even more.

Pack for wind, spray and a walk that takes longer than you think

Coastal paths are slow. Allow around three kilometres an hour, not four, and add time for ascent — a minute for every ten metres of climb is a reasonable rule — plus stiles, gates, mud and photographs. A route that looks like four hours on paper often takes five.

Take a windproof and waterproof layer even on a warm forecast, because headlands are exposed and sea breezes arrive without warning. Sturdy boots with real grip are essential on wet rock, clay and steep grass. Add water, food, a headtorch, a whistle, a basic first aid kit, sun cream and a charged power bank. A small sit mat makes a clifftop lunch far more pleasant.

On the day: edges, livestock and knowing when to turn back

Stay well back from cliff edges, especially where the grass looks undercut or cracked. Erosion is constant and the edge you stood on last year may not be there now. Do not climb fences or take shortcuts down to a beach unless there is a marked path. Keep dogs on a lead near livestock and near edges, and always close gates behind you.

Set a turnaround time before you set off and honour it. If the weather closes in, if the path is worse than expected, or if the tide is earlier than you thought, turning back is the right decision, not a failure. If you do get caught out — cut off by the tide, lost in fog, or someone injured — dial 999 and ask for the coastguard. Give a grid reference if you have one, and stay put somewhere safe and visible. Never enter the water to help a person or a dog in trouble; call for help and let trained rescuers do it. Plan well, and the coast will give you some of the finest days of walking you will ever have.
