Start With the Way Out

Most of us plan a hill day from the bottom up: car park, path, ridge, summit, home. The summit is the goal and everything else is detail. It is a habit worth breaking. The most useful planning on any British hill day happens in the other direction — working out, before you set off, where you could leave the route quickly and safely if the weather turned, someone turned an ankle, or the light started going.

An escape route is not an admission of weakness. It is what turns a committing day into a manageable one. Knowing that a broad shoulder drops you onto a track half an hour from the road changes how you feel on the summit ridge in a rising wind. You walk better when you know your exits.

Reading the Map for Escape Lines

Take the largest-scale map you can carry — 1:25,000 if you have it — and look at your route with fresh eyes, hunting for ways off rather than ways up. The features that give you a quick retreat are surprisingly consistent across these islands.

• Tracks and estate roads. Any mapped track leading downhill towards a public road is a gift. Note where it starts, not just where it goes; a track half a kilometre below a ridge is useless unless you know the ground between.
• Valleys and glens. Water almost always finds the easiest line. A stream running down towards habitation is usually a corridor, even if no path is drawn on it. Follow it on the map and check the contours for steepening.
• Forestry rides and clearfell edges. In conifer plantations, rides — the straight, unplanted lines — often run to a forest road. Fresh clearfell can be impassable, so check how recent the map is and be ready for the ground to have changed.
• Fence lines and walls. Not routes in themselves, but excellent handrails. A boundary running down to a valley floor lets you navigate in poor visibility with almost no compass work.
• Broad ridges and shoulders. A wide, gently angled spur is far friendlier than a narrow one. Look for where the contour lines space out.

Terrain That Looks Like an Escape But Isn't

Contours can lie to you, and some of the most inviting lines on paper are the worst ground on the hill.

• Tightly packed contours. Anything crowding together means steep ground, and in Britain that often means crags, scree or loose rock. What reads as a shortcut on the map can be a difficult descent you would not choose to reverse.
• Water crossings. A stream you stepped over in the morning can be a serious obstacle after heavy rain. Plan escapes that do not depend on fording anything above knee height.
• Bogs and deep heather. Flat, featureless ground marked with marsh symbols can be brutally slow. A two-kilometre escape across deep bog can take well over an hour.
• Steep grass. Wet, tussocky grass on a thirty-five degree slope is miserable and surprisingly slippery. It is rarely the quick way down you imagine it to be.

A useful habit is to note each escape on your route card with a grid reference for the point where you would leave the main route. That junction — the decision point — is the thing you need to identify on the ground, ideally with a distinctive feature to confirm you are in the right place.

Timing, Light and the Turn-Around Point

Escape routes are only useful if you have the time and the daylight to use them. Work out rough timings before you go, using something like Naismith's rule — about three kilometres per hour on the flat, plus a minute for every ten metres of ascent — then add a generous margin for the terrain you actually expect.

Set a turn-around time, not just a turn-around point. If you have not reached the summit by, say, two o'clock, the decision is made for you. On short winter days in the Scottish Highlands, the Lake District or Snowdonia you may be looking at barely seven hours of usable light, and much less if cloud is down. Aim to be off steep ground and back on a track well before dusk.

Build in a contingency: one hour of daylight in hand at the end of the day is a sensible rule for anything involving navigation in poor visibility.

Using Escape Routes on the Day

In practice, you rarely need them. But the moment you do — a twisted knee, a sudden squall, a companion who is struggling — is the worst possible moment to start reading the map from scratch.

So keep the options live. As you walk, glance at the map at each escape point and confirm what you would do here and now. If the cloud comes down, take a bearing before you need it. If the wind gets up on an exposed ridge, know which side your descent lies on. And be honest about the speed of your slowest member: a group moves at the pace of the person at the back.

Turning back is not a failure of ambition; it is the outcome a well-planned route is built to make easy, sensible and safe. Plan the exits first, and the summit takes care of itself.
