Safety Tips for Walking Beside Rivers in Winter

Winter Changes a Familiar Path

The stretch of river you walked all summer is not the same river in January. Flows are higher, the water is colder, and the banks that felt solid in July may be soft as a sponge after a fortnight of rain. None of this means you should stay indoors — winter rivers are some of the best places to watch wildlife, with kingfishers easier to spot against bare branches and otters more active in the quieter months. It simply means adjusting how you walk them.

British river water in midwinter often sits somewhere around 4–5°C, and cold water shock can hit within seconds of an unexpected plunge. That is the real risk on a riverside walk: not the walk itself, but the fall. The advice below is about keeping the fall from happening, and knowing what to do if the ground or the weather turns against you.

Start with Your Feet

Traction is the single biggest thing you can control. Wellies are excellent in deep mud but notoriously slippy on wet wooden boardwalks, metal stiles and stone steps, and many pairs have almost no tread left after a season of use.

• Choose boots with deep, soft lugs rather than hard, worn soles. Grip comes from the sole biting into mud and leaf litter, not from the boot being waterproof.
• Consider a walking pole — one is useful, two are better on icy towpaths. They give you three points of contact and take the shock out of a stumble.
• Pack layers and a spare pair of gloves. Wet hands in a cold wind lose dexterity quickly, and a dry pair in your bag makes the walk home far more comfortable.
• Carry a head torch. Winter light fades by half past three, and the last kilometre beside water is often the darkest.

Never Trust the Bank After Rain

Saturated soil behaves differently from dry soil. After heavy rain, the outer edge of a river bank can be undercut for a metre or more, with a lip of grass that looks perfectly solid until you put weight on it. Watch for these signs and turn back or move inland if you spot them:

• Cracks or slumps in the turf running parallel to the water's edge.
• Exposed roots or dribbles of muddy water leaking from the bank face.
• A hollow, spongy feel underfoot — stop and step back the way you came rather than forward.
• Grass that sags in a line where the soil behind it has already given way.

Walk a good metre back from the edge, and further on the outside of bends where the current cuts hardest. Avoid standing on frozen margins too; ice over moving water is thinner than it looks, and a frozen puddle tells you nothing about the depth beneath it.

Tell Someone Your Route

A short message takes ten seconds and saves hours of worry. Before you set off, tell someone where you are going, which path you plan to take, and when you expect to be back. If you are walking alone, agree a check-in time and stick to it.

It is also worth checking river levels and any flood warnings for your area the night before. If the gauge is rising steeply, plan a walk that stays away from the floodplain altogether. Wear something bright — a splash of colour on a grey afternoon is easy to spot from a distance — and leave a note on the dashboard if you park near a remote stretch. Always carry your phone somewhere genuinely waterproof rather than a coat pocket that leaks.

Flooded Sections Are Not a Shortcut

If the path disappears under water, that is your turnaround point. Wading is never sensible: you cannot see submerged roots, collapsed edging or lifted drain covers, and moving water above knee height can sweep an adult off their feet. Floodwater also carries sewage, agricultural run-off and sharp debris.

Do not be tempted to cut across the field beside it either — the same waterlogged ground can hold deep, boot-sucking mud. Retrace your steps, take a proper right of way around, or enjoy the walk on another day. A flooded riverside path will still be there next week.

Dogs, Swans and Disturbed Wildlife

Winter is hard on riverside wildlife, and every unnecessary flight burns energy that birds and mammals cannot spare. Keep dogs under close control near the water, and on a lead around swans, geese and any stretch with bankside cover.

If your dog does go in, do not follow it. Stay calm, move downstream of the exit point and call it to a shallow, gently shelving spot. Only dial for help if you or the dog are genuinely in difficulty — and never enter cold, fast water to retrieve an animal.

For everything else, a quiet approach and a pair of binoculars are all you need. Stand still, keep low, and let the river come to you. That is the whole pleasure of it: a flask in your pocket, grippy boots on your feet, and a proper British winter afternoon unfolding at its own pace.
