Why riverside paths come into their own after six o'clock

By early evening, an open field path can still be holding the heat of the day — dry grass, still air, low sun straight in your eyes. Step onto a path that runs beside a river under alders, willows and ash, and the change is immediate. Water and tree cover both cool the air, and a leafy canopy filters the light so you are walking in soft green shade rather than squinting into a glare.

There is a practical rhythm to it too. Riverside routes are usually flatter than ridge paths, which means you can walk further on tired legs and still be home before dark. The shade that makes them pleasant also keeps the ground damper, though, so the same path can feel quite different after a wet week. Treat a riverside walk as its own kind of outing rather than a shortcut version of a hill walk, and you will get far more out of it.

Choosing a route that suits the light you have

Be realistic about how far you will actually walk in the time available. A comfortable evening pace over flat ground, with a few stops to look at the water, is roughly three kilometres an hour. A two-mile loop with a bridge at the far end is a genuinely satisfying summer evening, and it gives you a natural turning point rather than an arbitrary one.

Before you set out, check three things:

• Where the path runs relative to the river. A route on the north bank under trees will be shadier in the evening than one on the south bank.
• Whether the loop needs a bridge, ford or stepping stones. Footbridges close for repair, and stepping stones can be under water after rain.
• Where the gates and stiles are. An awkward stile at dusk, with a dog and a rucksack, is much less fun than it looked on the map.

A 1:25,000 map of the area plus your county council's rights of way map will show public footpaths, bridleways and permissive paths. Mark your intended turn-around point and give yourself permission to shorten the walk if the light goes earlier than expected.

What to carry, and what to leave behind

Riverside evenings mean insects, so insect repellent belongs in your pocket, not at home. Look for a product containing DEET or picaridin and reapply it at the halfway point rather than once at the start. Long sleeves and thin trousers tucked into socks sound excessive in July, but they are the difference between a relaxed stroll and a hurried one on a still evening beside slow water.

A short kit list that genuinely earns its place:

• A small torch or head torch — the last twenty minutes of a walk are always darker under trees than they look from the car park.
• Antihistamine cream and a tick removal tool. Ticks like damp grass margins and the edges of riverside meadows.
• A litre of water between two people, even for a short walk.
• Blister plasters and a spare pair of socks if any part of the route crosses wet ground.

Leave behind anything you would not want to carry if the route turns out to be muddier or longer than planned. Light bags make for happier evenings.

After heavy rain: reading the bank underfoot

This is where riverside walking asks for a bit more attention than a field path. Fast-rising water undercuts banks, and an edge that looks solid from two metres away can be hollow beneath. Stay on the trodden line of the path rather than stepping onto the grassy lip above the water, especially where the bank curves and the current is fastest on the outside of the bend.

Watch for the usual suspects:

• Slippery roots and stones where the path dips to water level.
• Muddy gateways and cattle-poached ground, which can be ankle-deep and much slicker than it appears.
• Flood debris in long grass — branches, and occasionally wire or glass carried down by high water.
• Wooden boardwalks and steps that turn greasy with algae when wet.

A walking pole or a sturdy stick is genuinely useful for testing ground before you commit your weight to it. If a section looks washed out or the path has clearly slumped, turn back rather than finding a way around it. There will be another evening.

Insects, nettles and other small nuisances

Mosquitoes and midges are at their most active in the hour either side of dusk, particularly in still air near slow or standing water. A breezy stretch along the river will be far more comfortable than a sheltered backwater, so if you are being eaten alive, walk on rather than reaching for more repellent.

Vegetation matters as well. Nettles, Himalayan balsam and hogweed all grow thick on riverside margins, and the sap of the larger umbellifers can cause nasty blistering when combined with sunlight. Keep arms and legs covered through the overgrown stretches, and check yourself over for ticks once you are back, paying attention to waistbands, sock lines and the backs of knees.

Making the last hour count, then getting home comfortably

The reward for the damp and the insects is that riverside paths are alive in the evening. Bats flit over the water, herons lift off from the shallows, and swallows work the mayfly hatch along the surface. Sit still for five minutes at a bend and you will almost certainly see more than you would walking briskly past.

Plan the finish deliberately. Note a landmark about a mile from the end — a particular gate, a footbridge, a distinctive tree — so you know you are nearly home even as the light fades. Let someone know your route if you are walking alone, keep dogs to the path and away from nesting banks, and leave gates how you found them. Do all of that and a riverside evening becomes one of the easiest, loveliest habits of the summer.
