What to Pack for a Hike: The Complete Hiking Essentials Checklist
19 October 2026 (10 minutes-reading)
A backpack that digs into your shoulders, or worse, a first aid kit still sat on the shelf at home: two extremes, the same poor preparation. Packing well doesn't mean packing everything. At Picture, we stand by one idea: travel light but ready, never one without the other.
This hiking gear list adjusts to the length of your outing, the weather and your level. Enough to fill your backpack with the right choices, and nothing left to chance.

What are the Ten Essentials for hiking?
A sudden storm over the Lake District fells, a twisted ankle on a Snowdonia ridge, dusk closing in faster than planned on a Scottish Highland path: British hills rarely give you much warning. That's the whole point of the Ten Essentials, a system first put together by the American climbing group The Mountaineers in the 1930s and now the global reference for hiking gear . Whatever your level or the length of your outing, these ten categories cover the most common surprises: shifting weather, injury, running late.
Here is what each category covers in practice:
-
Navigation: an Ordnance Survey map and a compass, even if your phone still has signal.
-
Sun protection: sunscreen, sunglasses and a cap, useful even under grey skies.
-
Insulation: an extra warm layer in case the temperature drops.
-
Illumination: a head torch with spare batteries, essential if the walk runs late.
-
First aid: a compact first aid kit to clean and dress a minor injury.
-
Fire: a lighter or waterproof matches, useful if you're forced to shelter overnight.
-
Repair kit: a knife or multi-tool to deal with a torn pack or a split boot.
-
Nutrition: a reserve of food in case the day runs long.
-
Hydration: always more than the strict minimum for the planned route.
-
Shelter: an emergency blanket, tiny and almost weightless in the pack.
Here is a quick table to see the full set at a glance:
| Essential |
Why pack it? |
| Navigation (map, compass) |

💡 TIP: Before every departure, tick off your Ten Essentials on your phone or on a slip of paper tucked into the pack. Two minutes is enough, and the item you leave behind is usually the one you end up needing most on the hill.
What to put in your backpack for a day hike?
For a day hike, the equation is simple: stay light while staying ready for anything. No need to copy the full list for a trek, but some basics are non-negotiable, even for a few hours out.
Your standard pack for a day on the hills should hold:
-
Water in the right quantity, at least 1 to 1.5 litres depending on the weather and the distance.
-
An energy snack: a bar, dried fruit or fresh fruit to keep you going without weighing the pack down.
-
A lightweight windproof jacket, easy to compress, to deal with a sudden weather shift on the tops.
-
Sun protection: sunscreen, sunglasses and a cap, even under cloudy skies.
-
A small kit with enough to clean a blister or a graze.
-
A charged mobile phone, useful for navigation or raising the alarm if needed.
This base shifts with the terrain. A two-hour walk through a woodland in the Peak District doesn't call for the same vigilance as an 800-metre ascent in the Highlands. Always match your list to the season, the terrain and the forecast: clear skies at the car park can turn into a downpour once you gain height.
Beyond two hours of walking, think about a proper lunch. A full, portable meal (sandwich, cheese, fruit) works better than snacks alone and keeps the mid-walk slump at bay. It's also a chance to take a real break, sat on a boulder with a view: one of those small pleasures that make the climb worthwhile on their own.
🧥 ADVICE: Even on a sunny day, always slip a warm layer into your pack. A long break, a wind picking up or a change of aspect can drop the felt temperature by several degrees in minutes.
What to wear hiking to handle British weather?
A clear sky at the trailhead guarantees nothing once you're on the ridge. The wind picks up, the temperature drops, a shower catches you on the summit. Your kit needs to absorb these shifts without ending up stuffed in the bag. The answer comes down to one word: the three-layer system.
The three-layer system for heat and rain
The base layer sits against the skin and wicks away the sweat generated by effort. Skip cotton, which traps moisture: go for a technical fabric or merino wool, which keep performing even when damp.
Over that, the insulating layer holds body heat without weighing the pack down. A lightweight fleece or a packable down jacket depending on the season: the idea is to put it on or take it off in seconds, in time with climbs and breaks.
Finally, the outer layer cuts the wind and rain. A windproof jacket without PFCs, like the ones developed by Picture, does the job without releasing unwanted chemicals into the hills you're walking through. A waterproof jacket completes the kit as soon as the clouds roll in, which, in the UK, is usually sooner than you think.
Choosing your hiking boots for the terrain
The choice of hiking boots comes directly from the terrain and the elevation on offer. On an easy, well-maintained path, a low-cut shoe is plenty: lightweight, it leaves the ankle free and suits day walks perfectly.
On the fells, on technical ground or with a loaded pack, a mid-cut or high-cut boot becomes essential. It stabilises the ankle, guards against sprains and gives better grip on scree or steep slopes.
In warm weather, round out the kit with shorts and a breathable technical shirt: the goal stays the same, match the gear to the effort rather than to the morning forecast.
👟 ADVICE: Never head out on a big walk in brand-new boots. Break them in over a few shorter outings first: your feet will thank you for not discovering the blisters mid-route.
What food to take hiking?
The mid-climb energy crash is familiar to everyone. Heavy legs, flat motivation: it's usually the sign of poor fuelling. Your body burns through reserves on any sustained effort, and without regular top-ups, hypoglycaemia arrives faster than you think.
The answer is a handful of simple, effective choices. Energy bars remain a steady classic: compact, carb-rich, they slip into any pocket. Dried fruit (apricots, raisins, dates) delivers natural sugars and fibre without weighing anything in the pack. On the savoury side, a square of dark chocolate and a wedge of hard cheese round out the base, bringing fats and protein for the long haul.
Hydration matters just as much as food. Count around 0.5 litres per hour of walking, adjusted for heat and elevation: a summer walk in full sun can easily double that need. To drink without breaking your rhythm, the water bladder slid inside the backpack changes everything. Its hose stays within reach and encourages small, regular sips, far more effective than a big gulp every two hours.
💡 TIP: Space your snacks every 1 to 2 hours rather than waiting for the big hunger pang. Your energy stays stable and you avoid the slump that turns the end of the walk into a grind.
Always adjust the quantities to the length of your outing and the day's conditions. A full picnic on a three-hour loop is overkill, but on a full day in the hills, better to pack generously than to head back on an empty stomach.
How to choose a hiking backpack?
A poorly chosen pack can ruin an outing faster than a surprise downpour. Too small, and you're forced to leave an essential behind. Too big, and you end up carrying extras that press on your shoulders with every step.
The volume comes down first to the length of your outing. For a day hike, a 20 to 30 litre pack is plenty: water, snacks, outer layer and first aid kit all fit without excess. For several days, go for 40 to 60 litres, enough to add spare clothes and sleep kit.
Comfort matters as much as volume. A ventilated back panel limits excessive sweating in the lower back, and padded shoulder straps spread the load across the shoulders. But it's really the hip belt that makes the difference: adjusted properly, it shifts up to 80 % of the weight onto the hips rather than the spine.
On total weight, keep one simple rule in mind: never carry more than 10 % of your body weight on a day hike, and 15 to 20 % on a multi-day trek. Beyond that, fatigue sets in faster and the pleasure of walking fades.
Investing in good gear isn't a luxury, it's what lets you cover the distance without pain or frustration. For more detail on packing a hiking backpack properly, our dedicated guide will give you every key to leave light but prepared for anything.
Hiking gear list for multi-day treks
Setting off for several days changes the whole equation. It's no longer about comfort, but autonomy: your hiking gear now has to cover sleep, meals and the unexpected over the long haul.
What to pack for a long walk or multi-day trek
A long-distance walk keeps the whole day-hike base, then adds the essentials to see you through several days. First reflex: spare clothes, at least a full set of underwear and socks to keep damp from settling in.
A sleeping bag becomes a must, along with a minimalist wash kit (biodegradable soap, microfibre towel). If your stages pass through bunkhouses or hostels, a stove is optional. On a multi-day trek in full autonomy, it becomes essential for hot meals.
Everything depends on your accommodation: on a night in a hostel or bothy, a lightweight sleeping bag often does the trick. In wild camping, you need the full sleep system, which naturally weighs more.
Packing your rucksack for several days
Weight distribution makes all the difference on a stage of 15 or 20 kilometres. Place heavy items close to the back (stove, food, water) to keep a stable centre of gravity, and the bulky but light items (sleeping bag, clothes) at the bottom of the pack.
A rain cover protects the whole thing in prolonged showers, a detail that saves plenty of grief at altitude or when the weather closes in.
🎒 TIP: On some organised treks, luggage transport is handled by vehicle between stages. Check before you go, as it radically changes what you need to carry on your back.
To see the gap between the two formats at a glance, here's a short comparison:
| Criterion |
Day hike |
Multi-day trek |
| Pack volume |
20 to 30 L |
40 to 60 L |
| Sleep system |
None |
Sleeping bag + sleeping pad |
| Food |
Picnic, snacks |
Full meals, reserves for several days |
| Total weight |
3 to 6 kg |
8 to 15 kg depending on autonomy |
Always adjust this list to your type of overnight: hostels and bunkhouses lighten the load considerably, where full autonomy in wild camping means carrying every piece of comfort and safety yourself.
Wild camping checklist
Sleeping out under the stars, far from unnecessary comfort: that's the promise of wild camping. In England and Wales, note that wild camping is strictly limited (only legal in parts of Dartmoor and with landowner permission elsewhere), while Scotland allows it widely under the Scottish Outdoor Access Code. Wherever you pitch, this total autonomy changes the whole hiking gear calculation. No bothy to welcome you, no kitchen to feed you. Everything sits in your pack, and everything has to work.
On the sleep side, three items are non-negotiable. A lightweight tent shields you from wind and overnight damp. The sleeping bag is chosen for the forecast temperature, with a safety margin if the mercury drops. And under your back, an inflatable sleeping pad or foam mat insulates you from the cold rising from the ground, often more treacherous than the surrounding air.
Nomad cooking also calls for its own kit: a compact camping stove, a lightweight cook set, and something to light a flame if needed (waterproof matches or a backup lighter). Enough to put together a hot meal after a day's effort, without depending on any resupply point.
Before closing the bag, here is the wild camping checklist to tick off:
-
Sleep: pitched-and-tested tent, sleeping bag rated to the expected temperatures, inflatable sleeping pad or foam mat.
-
Cooking: stove, cook set, gas or fuel, waterproof lighter, water bottle or filled water bladder.
-
Comfort: head torch, dry spare clothes, bin bag to carry out your waste.
🏕️ ADVICE: Pitch your tent at home at least once before heading out. You'll save precious time on the ground, especially if night falls faster than you'd planned.
What to pack for winter hiking in the UK?
Winter changes everything. The cold sets in quickly, daylight fades in the early afternoon, and conditions can flip inside a few hours. What worked in summer no longer cuts it as soon as the thermometer drops.
Insulation becomes your top priority. A lightweight down jacket in the pack makes all the difference as soon as you take a break or the wind rises. Compact and easy to layer, it rounds out your three-layer system without weighing the pack down. Add a beanie , technical gloves and warm socks: your extremities are the first to suffer when temperatures drop below zero.
Also, think about adjusting your pace. Winter ground shifts under your feet: snow, ice, waterlogged earth. Lightweight microspikes and trekking poles secure your footing on slippery sections.
Before setting off, always check the local forecast and the Mountain Weather Information Service for the hills you're heading into. A walk that looks easy on paper can turn hazardous if a storm rolls in mid-afternoon. Keep a safety margin at all times: set off early, plan a bail-out route, and never ignore the first signs of cold-related fatigue.
🔥 TIP: Slip one or two hand warmers to the bottom of your pack, along with a hot drink in an insulated flask. That small gesture turns a frozen break into a welcome boost, especially when the wind picks up on the ridge.
What is Naismith's rule for hiking?
Setting off without a time reference is the quickest way to be caught out by heat or by nightfall. Naismith's rule, devised by Scottish mountaineer William W. Naismith in 1892, answers that exact problem with a simple formula: allow one hour for every 5 kilometres (3 miles) on the flat, plus an extra hour for every 600 metres (2 000 ft) of ascent. It's a solid baseline to calibrate your outing, not an exact science: slow it down for a loaded pack, difficult ground or less experienced walkers.
This figure doesn't replace the good habits that make the difference when things go wrong. Always tell someone close your route and your estimated return time. Keep a comfortable buffer in your timings: an underestimated climb or a twisted ankle, and your schedule unravels fast.
For navigation, the OS map stays your best ally, even with a fully charged phone. Check the mountain forecast before heading out, as it can change everything in a few hours in UK hills. And keep the emergency number in mind: for mountain rescue in the UK, dial 999 and ask for the police, then Mountain Rescue (112 works too and can be reached even on another operator's network).
📍 ADVICE: Before every departure, record your route and planned return on your phone or on a dedicated app. If you run late, those close to you will know exactly where to look, and the rescue services will save precious time.
Ready to pack your bag?
From a two-hour outing to an autonomous trek, good hiking gear is always chosen the same way: cover the unexpected without needlessly weighing down the pack. The Ten Essentials set the base, duration and weather fine-tune the rest.
A last check before you leave, a route shared with someone close, and you're set to enjoy the trail fully, whatever the season.
FAQ
What do people usually take hiking?
The essentials stay the same for most walkers: enough water, energy snacks, sun protection, something to navigate with and a first aid kit. Add a charged mobile phone for emergencies and a warm layer, even in fine weather. That base covers most of the surprises you'll meet on the trail.
Can you hike in trainers or do you need hiking boots?
On a flat, well-marked path, sturdy trainers can do the job for a short outing. As soon as the ground gets trickier (steep ascent, scree, exposed roots), hiking boots become essential for ankle support and grip. Beyond two hours of effort, it's not worth cutting corners.
How much water should you take for a hike?
Count between 1.5 and 2 litres of water for a standard day hike, more in heat or on sustained effort. Also think about sun protection: a hat, sunglasses and sunscreen round out your kit nicely to avoid heatstroke and sunburn on exposed ridges.
How can you cut pack weight without missing anything essential?
Favour multi-purpose kit: a windproof jacket that also handles rain, a knife that doubles as a tool and bottle opener. Drop the surplus (duplicate clothes, pointless gadgets) and keep only what answers a real need. A well-thought-out pack feels light while staying complete.
