Why the paper map still earns its place

A phone is wonderful until the rain arrives, the battery dies at the wrong moment, or a boulder field swallows your footing and the screen along with your confidence. A paper map never runs out of power. On a hill day in the Lake District, Snowdonia, the Pennines or the Scottish Highlands, a laminated 1:25,000 or 1:50,000 map and a simple compass remain the most reliable tools you can carry. The trick is learning to read them properly, so the symbols on the sheet become a picture of the ground beneath your boots.

Start by checking the scale. An Explorer map at 1:25,000 shows four centimetres to the kilometre, with field boundaries, walls, streams, crags and small paths marked in detail. A Landranger at 1:50,000 covers more ground but smooths out the finer features. For navigating open moorland, the larger-scale Explorer is usually the kinder choice.

Matching symbols to the landscape

The legend is not a formality. Spend ten minutes with it at home before you go, and the map begins to speak. Then test yourself on the hill: look at a feature in front of you, find it on the map, and confirm the symbol. That loop of looking, comparing and confirming is the whole skill.

• Contours show height and shape. On an Explorer, each line is five metres of ascent. Lines packed tightly together mean steep ground; widely spaced lines mean gentle slopes.
• Re-entrants and spurs are the folds of the land. Contours that form a V pointing uphill mark a valley or stream; a V pointing downhill marks a ridge or spur.
• Water appears in blue — streams, becks, llyns and tarns. A stream in a valley bottom is one of the most useful handrails you can follow.
• Walls and fences are black lines, sometimes with small tick marks. They are excellent boundaries for keeping a bearing honest.
• Crags and screes use hachures and grey shading, and they warn you where a direct line will turn into a scramble.
• Paths are broken black lines, while rights of way may be marked in green or orange. Treat them as a guide, not a guarantee — many fade on the ground.

Setting your map to north

A map only makes sense when it is aligned with the world. Lay it flat, place your compass on the sheet, and rotate the whole map until the grid north lines run parallel with the compass needle pointing north. Better still, use the compass to find north and then turn the map so its top edge faces that way.

One small complication: magnetic north drifts slightly from grid north. In the UK the difference is currently small — a degree or two in most places — and it is printed in the margin of every Ordnance Survey sheet. For everyday walking it rarely matters, but check the margin and keep it in mind for long legs across featureless ground. Once the map is set, everything lines up: the ridge in front of you sits on the paper exactly as it sits in the landscape, and you can read your position at a glance.

Taking a bearing across open moorland

When there is nothing to aim at but heather and sky, a bearing is your best friend. Here is the sequence, steady and unhurried:

• Place the compass on the map with its direction of travel arrow pointing from your position towards your target.
• Turn the bezel until the orienting arrow lines up with the grid lines, pointing north on the map.
• Lift the compass and hold it flat at chest height. Turn your body until the red end of the needle sits inside the orienting arrow — often remembered as "put red in the bed".
• Look up along the direction of travel arrow. Pick a distant feature on that line — a boulder, a cairn, a distinctive patch of scree — and walk to it. Then repeat.

Do not simply stare at the compass and walk; you will drift. Aim at a landmark, walk to it, and take a fresh bearing if needed.

Pacing, timing and catching features

A bearing tells you the direction, not the distance. Count your paces over a known stretch — most adults cover roughly 100 metres in 60 to 70 double paces on flat ground, and rather more uphill. Combine that with timing: a common rule of thumb is about five kilometres per hour, plus one minute for every ten metres of ascent, adjusted for rough ground, bog and heavy packs.

Finally, use catching features and handrails. A catching feature is something beyond your target that tells you if you have overshot — a stream, a wall, a forest edge. A handrail is a linear feature you can follow alongside, such as a fence or a beck, which keeps you on track without constant compass work. Deliberately aiming a little to one side of your target and then following the handrail in is a classic trick on featureless moorland, and it has saved many a tired walker from wandering off course.
