Navigation is the technical core of the Mountain Leader Award. Everything else – group management, risk assessment, campcraft – is built on a foundation of being able to move competently and confidently through mountain terrain without getting lost. If your navigation isn’t solid, nothing else matters.
This guide sets out the specific navigation skills required for ML training and assessment, and how to develop each one during your Quality Mountain Days.
The Navigation Standard Expected at Training
When you arrive at an ML training course, the expectation is that you already have sound navigation skills. This is explicitly stated by MTUK: training is not where you learn to use a compass. It’s where you refine existing skills, learn to apply them under pressure, and learn to teach them to others.
In practice, this means being able to:
- Navigate accurately on compass bearings across featureless terrain
- Read contours to anticipate and interpret the ground ahead
- Use timing and pacing to measure distance walked
- Make confident route decisions in poor visibility
- Identify your location on the map using terrain association and resection
- Navigate without GPS dependency
If you arrive at training still hesitant with a compass, you’ll spend the five days catching up rather than progressing. The candidates who get the most out of training are those who arrive with the basics sorted and use the course to sharpen them.
Map Reading at Mountain Leader Standard
At ML level, map reading goes well beyond identifying paths and summits. The key skill is contour interpretation – reading a map and understanding the three-dimensional shape of the terrain ahead of you, before you can see it.
Contour Interpretation
Practise identifying these features from the map, then confirming them on the ground:
- Spurs and re-entrants – fingers of high ground and the valleys between them
- Cols and saddles – low points between two high points
- Cliffs and crags – very close contours or cliff symbols; know how to identify ground too steep to travel
- Plateaux – areas with widely spaced contours; deceptively featureless on the ground
- Convex vs concave slopes – on a convex slope you can’t see the base; on a concave slope you can. This affects navigation decisions and group safety
- Escape routes – before you leave a path, know where the ground falls away and where you could descend safely if conditions deteriorate
The goal is to be able to look at a section of map and visualise the ground without needing to be standing on it.
Scale and Distance
At 1:25,000 scale, 4cm on the map equals 1km on the ground. You should be able to estimate distances quickly by eye and confirm them through timing and pacing. Practise until it becomes instinctive.
Always check the map’s magnetic variation note. In the UK, grid north and magnetic north differ by a small but meaningful amount, and applying the correct variation is a basic requirement of accurate compass work.
Compass Skills
A compass is only as useful as the person holding it. The ML expects you to be fluent with a baseplate compass – not just vaguely familiar.
Taking a Bearing
The standard method on a Silva-type baseplate compass:
- Place the compass on the map with the long edge between your current position and your target
- Rotate the bezel until the orienting lines align with the north-south grid lines, north arrow pointing to map north
- Apply magnetic variation (add for most of the UK – check your map)
- Hold the compass flat, rotate your body until the red end of the needle aligns with the orienting arrow (“red in the shed”)
- Travel in the direction the compass arrow is pointing
This should be muscle memory before you attend training. Practise it until you can take an accurate bearing quickly, under pressure, with cold hands and rain on your map.
Following a Bearing
Taking a bearing is only half the skill. Following it across ground – especially featureless terrain – requires discipline. Identify a feature in line with your bearing as far ahead as you can see, walk to it, recheck your bearing, repeat. In thick mist where you can see only a few metres, this becomes a navigation conversation you’re having with yourself constantly.
Back Bearings
A back bearing (180 degrees from your walking bearing) lets you check you haven’t drifted. Periodically look back along your route and check the feature you’ve come from is on your back bearing. If it isn’t, you’ve moved off line.
Triangulation and Resection
If you’re unsure of your position, you can fix your location by taking bearings to two or three known features visible on both the map and the ground. Where the back bearings cross is your position. This is slower than terrain association but highly accurate and a solid skill to have under your belt.
Timing and Pacing
Timing and pacing are how you measure distance walked, particularly on featureless terrain where there are no intermediate features to fix your position.
Naismith’s Rule gives a rough estimate of hill walking time: 5km per hour on the flat, plus 10 minutes per 100m of ascent. Adjust for your personal pace and conditions. In full winter kit, on boggy ground, into a headwind, you’ll be significantly slower.
Pacing lets you count off distance. You need to know how many of your double paces (every time your right foot hits the ground, for instance) equal 100m. This varies by terrain and gradient, so calibrate on different surfaces – flat path, open moorland, steep uphill.
In poor visibility navigation, timing tells you when you should have arrived. If your timing says you should be at the col and there’s no col, you’ve either moved off bearing or your distance estimate was wrong. Use the discrepancy to fix your position.
Night Navigation
Night navigation is a specific ML requirement and one that candidates often under-prepare for. The skills are the same as daytime navigation, but you’re applying them with reduced visibility, often cold and tired, with a head torch narrowing your field of view.
Key differences to practise:
- Features are harder to identify at distance – you rely more on timing and pacing, less on terrain association
- Contours become more important – you’re often feeling the shape of the ground underfoot as much as seeing it
- Head torch management – angling your torch to read the map without destroying your night vision
- Pace and confidence – moving decisively in the dark takes practise; hesitation compounds navigation errors
Build at least a few night navigation sessions into your mountain days log before training. Evening sessions on accessible moorland are fine, they don’t all need to be full mountain days.
Route Finding in Poor Visibility
Poor visibility navigation is where the ML separates competent walkers from genuinely skilled mountain navigators. When the cloud is down, the ground looks featureless, and your only tools are compass, timing, and contour reading, the skills above come together.
Practise making navigation decisions in poor visibility as often as conditions allow. Don’t wait for better weather – use the mist. Use it as training, and make deliberate navigation choices rather than just following the path.
Route selection in poor visibility also means hazard awareness: knowing where the ground becomes dangerous, where cliffs are on the map, where descent routes are acceptable and which are not. This is part of the group management skill set at ML level, but it starts with sound navigation.
Teaching Navigation to Others
An element of the ML assessment is your ability to explain navigation to group members and lead them through navigationally demanding terrain. You need to be able to brief clearly, check understanding, and adjust your explanations for different experience levels.
Start practising this before your training course. On days out with friends or family who are less experienced, explain your navigation decisions out loud. Why are you taking this bearing? What feature are you heading for? What will you see when you arrive? How long will it take?
This builds the communication habit that assessors will be looking for.
The Right Gear for Developing Navigation Skills
Compass: Get a Silva Expedition 4 or the Suunto A-10. The Expedition 4 has a longer baseplate (useful for taking accurate bearings on large-scale maps), a declination adjustment, and a clear, easy-to-read bezel. Use it on every mountain day, regardless of whether you could navigate by sight.
Maps: OS Explorer (1:25,000) for the area you’re walking in. Buy the sheets, not just app access – you need to be comfortable handling a paper map in wind and rain. A waterproof map case from Ortlieb or Aquapac is worth the small investment; a ruined map in a downpour is an avoidable problem.
Head torch: For night navigation sessions, the Petzl Actik Core is a solid choice – rechargeable, genuinely bright, and with a red light mode that preserves your night vision when reading the map.
Waterproofs: Poor visibility often means poor weather, so the two tend to come together. Getting your navigation practice in when conditions are at their worst means having kit you trust. A jacket like the Rab Kinetic Plus that’s genuinely waterproof rather than shower-resistant makes a real difference to how long you stay out and how much you learn.
Navigation isn’t a skill you arrive at. It’s an ongoing process of getting better, building up a bank of decisions made under pressure, terrain read correctly, and bearings followed across ground. The candidates who perform well at ML assessment aren’t those who crammed navigation in the months before – they’re the ones who’ve been navigating seriously for years.
