Practical tips and step-by-step instructions to help you master map and compass skills on Britain’s trails. You don’t need to be an orienteering expert, but with these basics you’ll be safer and more confident.
Getting Started with Compass Navigation
On Britain’s hills and moors, conditions can change in minutes. A clear ridgeline can vanish into mist, and what looked like an obvious path can suddenly feel disorientating. In these moments, a compass is more than just a bit of kit — it’s a lifeline.
The skills in this guide will give you the confidence to use a compass effectively when it matters most. Think of it as a practical starting point: enough to keep you safe if your phone dies, or you simply need to navigate back to a trail in poor visibility.
We’ll cover the basics every UK hiker should know — the key parts of a compass, how to take and follow a bearing, and how to avoid common mistakes. If you’re new to the hills, our Beginner’s Guide to UK Hiking is a great place to start.
Why You Still Need a Compass
With all the navigation apps, digital maps, and GPS units we carry around these days, it’s easy to wonder whether a compass still has a place in your pack. After all, your phone can pinpoint your location on a map in seconds — when it’s working properly.
But here’s the thing: technology isn’t foolproof. Batteries die, screens crack, GPS signals drop, and sometimes your device simply decides to give up halfway through a hike (it’s happened to me more than once). And when you’re miles from the nearest road, that’s the last problem you want.
A compass, on the other hand, never runs out of power or loses signal. It’s one of the few bits of kit that will always work — as long as you know how to use it. Learning to navigate with a map and compass isn’t just a backup skill; it’s part of becoming a confident, self-reliant hiker.
What a Compass Can Do (and Why It Matters)
A compass might look simple, but it’s capable of much more than just pointing north. Once you understand the basics, it becomes a powerful tool for reading the landscape and making confident decisions on the trail. Here are a few of the key things a compass allows you to do:
-
Know your direction of travel — This is called your heading.
-
Align your map with the landscape — Known as setting the map, this helps your map match what you see around you.
-
Find the direction of a feature or destination — This is called taking a bearing.
-
Walk accurately in a straight line — Known as following a bearing.
Why This Matters for UK Hikers
Britain’s trails often cross open moorland, misty ridgelines, and featureless plateaus where landmarks can vanish. Knowing the basics of your compass means you’re not left guessing or blindly following a path that might not lead where you expect.
Understanding the Compass
Before we dive into navigation, it helps to get familiar with the compass itself. Don’t worry — this isn’t a deep dive into every possible feature, we’ll focus on the essentials you’ll actually use on a UK hike.
The Main Parts of a Compass
Most hikers in the UK use a baseplate compass — they’re lightweight, reliable, and designed to be used with Ordnance Survey (OS) maps. The key parts are:
Baseplate
The clear plastic rectangle you place on your map. It usually has rulers for map scales (useful with OS maps).
Direction of Travel Arrow
This hows you which way to walk once you’ve set a bearing. This is usually located at the top/front edge of the baseplate.
Rotating Bezel (Compass Housing)
The dial that turns, marked with degrees (0–360°) and the cardinal points (N, E, S, W).
Magnetic Needle
The Red End of the needle always points to magnetic north.
Orienting Arrow
Inside the bezel; the orienting arrow is usually red, and looks rather like a tall, little red shed ⇑
Orienting Lines
Also inside the bezel; these lines align with the map’s north-south grid lines that are on all OS Maps.
👉 Pro Tip: If you’re buying your first compass, look for a well-made baseplate model from trusted UK brands like Silva or Suunto. They’re widely stocked at Go Outdoors, Amazon UK and many outdoor retailers.
How to Use a Compass and Map Together
Add a map, and your compass becomes a complete navigation system.
A compass on its own is useful, but it really shines when paired with an Ordnance Survey (OS) map. Together, they give you the tools to navigate almost anywhere in the UK, even in poor visibility.
Orienting Your Map
Firstly lets get your map in sync with the real world. Think of your map as a snapshot of the landscape—you just need to “line it up” so it makes sense
-
Lay your map flat in front of you.
-
Set your compass on the map (doesn’t matter how it’s lined up).
-
Without moving the map or compass, turn the bezel until the orienting lines inside the bezel housing run parallel with the map’s north-south grid lines
-
Finally, slowly rotate the map (and compass together) until the red end of the magnetic needle points straight up to the top of the map and sits inside the orienting arrow (commonly known as putting “red in the shed”).
The image shows what this looks like when completed successfully. Now, when you look from map to horizon, what you see on paper should line up with the terrain around you.
Taking a Bearing (Step by Step)
Once you’ve oriented your map, the next skill is taking a bearing. A bearing is simply a direction, measured in degrees from north, that guides you from one point to another. For example: 135° means you’re heading southeast.
Don’t worry if that sounds technical — the process is straightforward once you’ve done it a few times.
Step 1: Place Your Compass on the Map
-
Lay your compass flat on your OS map.
-
Line up the edge of the baseplate between where you are and where you want to go. Think of it as if you were going to use the compass edge like a ruler to draw a straight line between the start and end points on the map.
-
Make sure the direction of travel arrow points from your start point to your destination.
Step 2: Rotate the Bezel
-
Without moving the map or compass, turn the bezel until the orienting lines inside the bezel housing run parallel with the map’s north-south grid lines.
-
Be sure the orienting arrow inside the bezel is pointing north on the map (not south — a common beginner mistake!).
Step 3: Read the Bearing
-
The number at the bezel’s index line is your bearing in degrees – for now just make a note of it in-case you inadvertently move the bezel while walking and need to realign it.
Step 4: Line Up with the Landscape
-
Now pick up the compass and hold it flat in front of you at chest height.
-
Rotate your whole body until the magnetic needle lines up inside the orienting arrow – “red in the shed”.
-
Now the direction of travel arrow points exactly where you need to walk.
Following a Bearing on the Ground
Don’t stare at the compass — pick a landmark in line with your arrow and head for it.
Once you’ve set a bearing on your compass, you can:
-
Follow the direction of travel arrow, but don’t just stare at the compass. Look ahead and pick a visible landmark (a rock, tree, or ridge) in line with your direction, then walk towards it.
-
Re-check your compass regularly, especially if the landscape is featureless.
-
If you reach the landmark, simply repeat the process.
This is especially handy in featureless UK terrain where paths aren’t always clear — for example, Dartmoor’s open moorland, the Scottish plateau tops, or the Pennine bogs.
Combining a Compass with Map Features
-
Check against landmarks: Use the compass to confirm that the hill, valley, or woodland you see in the distance matches what’s on the map.
-
Avoid parallel errors: In the UK, many paths and walls run in similar directions. Always double-check the compass bearing matches your intended line, not a nearby parallel track.
-
Pacing and timing: On flat moorland, where there are no features, compass bearings combined with pacing (counting steps) or timing (minutes walked) help you estimate distance. See our guide to How Fast Should You Walk When Hiking? for an in-depth look.
👍 Beginner Reassurance: Think safety, not precision. You don’t need pinpoint orienteering accuracy for most UK trails. A bearing accurate to within a few degrees will keep you on course until you pick up another feature or path.
A Quick Story from the Welsh Hills
I learned the value of these skills on a misty day in Snowdonia, climbing up towards Cadair Idris. The morning started clear, but halfway up the Pony Path the clouds rolled in, and within minutes the ridgeline ahead vanished.
Several walkers around me had their phones out, only to find patchy signal, so their online maps could not update. I unfolded my OS map, set a quick bearing with my compass, and picked a rocky outcrop to aim for. A few short legs later, I was back on the main path and heading towards the summit safely.
It wasn’t advanced navigation by any means — but it proved that a few simple compass skills can make the difference between pushing on with confidence or feeling stranded in the fog.
The best part – most of the other walkers who saw me using a map and compass had put away their phones and followed me! 😮
Final Thoughts & Key Takeaways
Using a compass doesn’t need to feel intimidating. You don’t have to be an orienteering expert or memorise dozens of advanced techniques. What matters is having the confidence to use a few simple skills when you need them most.
On UK hills and moors navigational confidence really matters – whether it’s the Cairngorm plateau, the Brecon Beacons, or on a long-distance trail like the West Highland Way — weather and visibility can change in minutes. A compass, paired with a paper OS map, gives you a safety net no phone or app can fully replace.
Key Takeaways
-
Start simple: Learn the main parts of your compass and how to set a basic bearing.
-
Practise locally: Build confidence on easy trails before you need it in the mountains.
-
Pair with a map: Always carry and use an Ordnance Survey map alongside your compass.
-
Don’t stress precision: A bearing that’s “good enough” is often all you need to get safely back on track.
-
Use tech wisely: GPS and phone apps are great tools, but treat them as a backup, not your only navigation method.
Mastering even these basics means you’re far better prepared than many hikers on Britain’s trails. The next time the mist closes in or your phone battery dies, you’ll know you’ve got the skills — and the confidence — to keep moving safely.

FAQ: Compass Use for UK Hikers
Do I need to worry about magnetic variation in the UK?
Not really. Magnetic variation (the difference between grid north and magnetic north) used to be a big factor in navigation, but in the UK today it’s very small — usually just a degree or two. For beginner navigation, that’s not enough to affect your safety. Just follow the steps in this guide and you’ll be fine.
Can I use a phone compass app instead of a real compass?
Phone compasses can work, but they’re easily affected by metal objects, signal issues, or drained batteries. A traditional baseplate compass never runs out of charge and is far more reliable in the hills.
What’s the best compass for beginners in the UK?
A simple baseplate compass, such as the Silva Expedition 4 or Suunto A-30, is ideal. They’re accurate, durable, and widely available from UK outdoor retailers.
Should I carry both a compass and a GPS?
Yes, absolutely. Think of your GPS or phone app as a brilliant backup, but your compass and paper map as the non-negotiable foundation. If one fails, you’ve always got the other.
How much practice do I really need?
Not much to start with. Spend a couple of hours on local walks practising bearings and orienting your map. The key is to be familiar enough that, if the mist rolls in, you won’t panic.
