Check the forecast before you pack a single thing

The Scottish hills can serve up four seasons between the car park and the summit. Before you touch your rucksack, look at a mountain-specific forecast. Check wind speed and direction, cloud base, precipitation, and temperature at height. A low cloud base and forty-mile-per-hour gusts will change your route far more than a bit of drizzle. Look again on the morning you leave, because a forecast from three days ago is only a rough guide. Tell someone your intended route, your estimated return time, and what you are wearing and carrying. If the forecast is marginal, choose a lower glen walk or a circular route with escape options. The hills will still be there next weekend.

Layering is your real waterproofing

Comfort in changeable upland weather comes from managing moisture and warmth, not from one magic jacket. Start with a base layer that moves sweat away from your skin. Add insulation in the middle, then protect it all with a shell. Carry a spare warm layer in a dry bag, even in July. When you stop for lunch, put it on before you cool down.

• Base layer: synthetic or merino wool. Avoid cotton, which soaks up sweat and chills you when you stop.
• Mid layer: fleece or a light synthetic jacket. This is your main warmth while walking.
• Shell: a waterproof jacket with a hood that adjusts and taped seams. It should fit over your layers without restricting your arms.
• Spare insulation: a lightweight down or synthetic jacket for stops, summits and emergencies.
• Hat, gloves and a buff: thin gloves and a warm hat weigh almost nothing and save a weekend.

Two thin layers beat one thick one. You can vent, remove or add as the glen turns into a ridge and the wind picks up.

Waterproofs, boots and the small comforts

Waterproof trousers are not optional in the Scottish hills. Full-length trousers with side zips let you pull them on over boots without sitting down in a puddle. Keep them near the top of your rucksack, not buried at the bottom. A rucksack liner or dry bags will keep your spare clothes, sleeping bag and map dry even if rain gets past the pack cover.

• Boots: waterproof, with a grippy sole and a comfortable fit. Wear them in before a big weekend.
• Socks: wool or synthetic, plus a liner sock if you blister easily. Pack a spare pair.
• Gaiters: useful for boggy ground, heather and loose scree.
• Blister plasters and tape: deal with hot spots early.
• Map case: a waterproof one, so your paper map stays readable.

Small comforts matter on a long day: lip balm, sunscreen, midge repellent in summer, and a tick remover. A sit mat or a square of foam makes a damp lunch stop civilised.

Food, water and the trusty flask

Hill walking burns more energy than a gentle lowland stroll, and appetite can vanish in cold wind. Pack food you actually enjoy and can eat with gloves on. A flask of hot soup, tea or coffee is a morale-boosting luxury on a cool summit. Fill it with boiling water at home, then wrap it in a spare fleece or sock for extra insulation.

• Water: one to two litres for a day, more in heat or on a long route. A filter or purification tablets give you options from streams.
• Flask: hot drink for the top, or cold water if the day is warm.
• Snacks: oatcakes, cheese, nuts, dried fruit, chocolate, flapjack. Eat little and often.
• Emergency rations: a spare cereal bar or packet of nuts that stays in your pack for the walk out.

If you are staying overnight in a bothy or camping, add a simple evening meal, a stove, fuel and a headtorch. Keep the flask and snacks accessible so you do not have to unpack everything at a windy col.

Navigation and safety kit

A reliable map and compass are still the gold standard. Choose a 1:25,000 or 1:50,000 map of the area, keep it in a waterproof case, and know how to set the map and take a bearing. A phone with offline maps and a power bank is a useful backup, but cold weather drains batteries and signal disappears in glens. Do not rely on a single device.

• Compass: a simple baseplate compass is enough if you have practised.
• Headtorch: with spare batteries. A wrong turn can make a short day much longer.
• Whistle: six blasts, pause, repeat is the international distress signal.
• Emergency shelter: a bothy bag or group shelter protects you from wind and rain while you plan.
• First aid kit: plasters, blister care, painkillers, and any personal medication.

Check the kit before you leave. A headtorch with flat batteries is dead weight. A compass with a bubble is a poor friend in mist.

Packing the rucksack for a comfortable weekend

Pack heaviest items close to your back and high enough to sit between your shoulder blades. Keep waterproofs, hat, gloves, flask and snacks near the top or in side pockets. Use dry bags for spare clothes, sleeping bag and electronics. If you are wild camping, split the load with your walking partner: one carries the tent, the other the stove and fuel.

For a weekend based in a village or hostel, carry a small dry bag of evening clothes and leave the rest in the car or accommodation. For a bothy or camping trip, add a sleeping bag, mat, stove and enough food for two days. Weigh your pack at home. Aim for comfort rather than bravado, because a heavy pack makes every boggy step harder.

Finally, dress for the walk rather than the car. Start slightly cool, with your shell and spare layer in the pack. Check that the flask is sealed, the map is in its case, and your route is left with someone reliable. Then step out, look at the cloud, and enjoy the hills on their own terms.
