Autumn is arguably the best season for a short hike in the UK. The crowds thin out, the woods turn gold, and the air has that clean, sharp edge to it that makes a flask of tea taste like a small triumph. But shorter daylight, wetter ground and quicker-changing weather mean a two-hour walk in October asks more of your daypack than the same route in June. The good news is that a well-chosen kit weighs very little. This is what to carry for a half-day autumn hike, and why each item earns its place.

Start With the Right Daypack

Everything below has to fit somewhere, so choose the bag first. For a short autumn walk, a pack of around 15 to 20 litres is ideal: big enough for a waterproof jacket, a flask and a spare layer, small enough that you won't be tempted to overfill it. Look for a padded back panel, a simple hip belt and at least one side pocket you can reach without taking the pack off. That pocket is where your water bottle lives, and you will drink far more if you can grab it on the move.

Before you leave, check the zip pulls and give the straps a tug. A bag that fails halfway round is worse than a heavy one. Line it with a dry bag or a sturdy bin liner if rain is forecast — even "waterproof" packs leak at the seams after an hour of steady drizzle.

Water and Food for a Shorter Walk

It's tempting to think a two-hour walk needs no fuel. In practice, cool air and muddy climbs burn more energy than you expect, and low blood sugar turns a pleasant ramble into a trudge.

• Water: around 500ml to 1 litre per person for a half-day, more if it's mild or you're climbing. A vacuum flask of hot tea or soup is one of autumn's great pleasures.
• Slow-release snacks: oatcakes, nuts, flapjack or a decent sandwich. Something with fat and fibre keeps you going better than a sugary cereal bar, which spikes and then drops.
• One spare snack more than you think you need. It weighs almost nothing and covers a wrong turn or a slower-than-planned return.

Keep food in a sealed bag. Autumn is peak season for inquisitive squirrels, and a chewed-through rucksack strap is a sad way to end a walk.

Navigation and a Charged Phone

Familiar paths look different under fallen leaves and low sun, and forestry tracks that were obvious in summer can vanish entirely. Carry a paper map of the area you're walking, folded into a clear pouch, and know how to read it. A compass is small and light; even if you never use it, it means you can reorient yourself if the path disappears. Note your grid reference at the start.

Your phone is a useful backup, not a primary tool. Cold weather drains batteries quickly, so start with a full charge, keep the handset in an inside pocket close to your body, and consider a small power bank. Tell someone at home where you're going and when you expect to be back — this is the single most valuable piece of preparation you can do, and it costs nothing.

Waterproofs, Warmth and Layers

Autumn weather changes its mind. A sunny start can turn into a cold, horizontal drizzle by mid-afternoon, and standing still to admire a view chills you fast. Pack for the worst hour, not the first one.

• A waterproof jacket with a hood, taped seams and decent breathability, not just a showerproof shell.
• Waterproof overtrousers if there's any chance of rain or wet grass. They weigh little and transform a soggy walk.
• A warm mid-layer — a fleece or light insulated jacket — for stops and summit snacks.
• A hat and thin gloves. Ears and fingers feel the cold first, and both take up almost no room.
• Spare socks in a dry bag, because autumn paths are muddy and stream crossings happen.

The principle is simple: start slightly cool, add layers when you stop, and strip them off again as soon as you warm up. Damp clothing from sweat chills you faster than the air does.

A Small First Aid Kit and Just-in-Case Items

You don't need a field hospital. You do need enough to handle a scrape, a blister or a headache without cutting the walk short.

• Plasters and blister plasters, plus a small roll of tape.
• Antiseptic wipes and a couple of gauze pads for grazes on a slippy descent.
• Painkillers you know you can take, and any personal medication.
• A head torch with fresh batteries. Autumn dusk arrives before you expect it, and a torch turns a late return into a minor inconvenience rather than an emergency.
• Tissues, a small bin bag for litter or wet kit, and a whistle attached to your pack strap.

A foil emergency blanket is roughly the size of a pack of cards and worth carrying on any walk where the weather could turn. Add a tick remover if you're heading through long grass or bracken — autumn is still tick season.

Packing It Well

Weight distribution matters as much as contents. Put heavy items like water and food in the middle of the pack, against your back, and keep things you'll want on the move — water, snacks, gloves, map — in outer or lid pockets. Everything else should be waterproofed, either in dry bags or a lined compartment.

Finally, weigh the finished pack. If it feels heavy for a short hike, you've probably packed for a long one. Trim it, then get out and enjoy the season: the low light, the smell of wet leaves, and the particular pleasure of a hot drink at a viewpoint with nobody else around. That's what autumn walking is for.
