Knowing how to take a bearing is essential knowledge when navigating through the backcountry with a map and your best compass. A bearing enables you to head in the right direction with confidence, even if you can’t see more than a meter ahead – a common occurrence in our wilderness regions. Whether you’re hiking at night, through thick fog or in a winter whiteout, knowing how to take a bearing will help you out of potentially difficult situations.

In today’s digital world, the art of traditional navigation is practised by fewer and fewer people. With GPS devices and route planning apps a common sight on the trails, technology has made navigating your way through the outdoors easier, quicker and more convenient. However, we never head for the hills and mountains without a map and compass in our hiking backpack.

A map and compass won’t run out of battery or fail in cold weather, leaving you stranded without the means to navigate effectively should the conditions change. Plus, there’s definitely something rewarding about finding your way through the wilderness without modern technology, only relying on your own navigational nous.

To effectively take a bearing, you should already know how to read a map and how to use a compass. Once you’ve got these basics in place, you’re ready. Just follow our step by step guide and get practising.

How to take a bearing

A great way to practise your navigation is to head out on a remote wild camp and use it as a base. You can develop your skills on a hike in the daytime and don your headlamp for some night navigation once the sun has set. That's what we did when we took our 2-person tent to Wales' Brecon Beacons National Park to practise our nav.

This is our step-by-step guide:

1. Find your location on the map

When you take a bearing, you need to know where you are (Point A) and where you want to go (Point B). The first thing you need to do is triangulate to work out exactly where you are and match this to the map. Use terrain features to do this, using fixed natural features first – such as gradients, crags and rivers – and then confirming your judgement using human features, like paths, walls and fences, as these are more liable to change over time.

Of course, if you need to take a bearing it may be because visibility is low. Perhaps the cloud has rolled in or perhaps it’s the dead of night. When this is the case, working out exactly where you are on a map is much more difficult. In these circumstances, it’s a good idea to cross reference with the map every time you arrive at an obvious feature, such as a summit, a building, a clear junction of paths, a waterfall etc. It’s worth reiterating: there’s no point taking a bearing unless you know where you are on the map.

2. Estimate the bearing between Point A and Point B

So, you know where you are on the map, this is Point A. You’ve figured out where you want to be, this is Point B. It’s useful, especially in low visibility, if Point B is something that should be quite an obvious feature when you arrive there.

It’s a good idea to make an estimation of the bearing because this will give you more confidence when you come to measure it accurately. It also ensures one little lapse in concentration doesn’t lead to a big navigational error, such as getting north and south mixed up. 

Study your map and estimate what you would expect the bearing to be. To do this, Look at the direction of travel between Point A and B on the map. If it’s between north and east, you would expect a bearing between 0 and 90 degrees – closer to 0 if it’s broadly north and closer to 90 if it’s broadly east. If the direction of travel is between east and south, you’d expect a bearing between 90 and 180 degrees. South and west is 180 to 270 degrees and west to north is 270 to 360 (or 0 – as you’ve come full circle) degrees.

Point B is a stone circle, which is clearly marked on the map. The direction of travel between Point A (Gwal y Cadno) and Point B is broadly north, with a little bit of west. So, the bearing is definitely going to be between 270 and 360 (which is also 0) degrees and closer to 360. We could probably make an estimate of a bearing somewhere between 330 and 350 degrees (Image credit: Alex Langfield)

3. Line up Point A and Point B using your map and compass

What often confuses people when they are learning to take a bearing is that the compass’s red north-facing needle does not come into play until you’ve put the map away. It almost seems counterintuitive because the north needle is what immediately springs to mind when we think about compasses. So, to reiterate, you don’t need to worry about the north-facing needle when calculating a bearing until you put the map away.

Bring your compass to the map and line up Point A with Point B using the straight edge of your compass, or the forward-facing lines on the base plate.

4. Align the map grid with the compass’s orienting lines

Being careful not to move the baseplate, rotate the compass housing (often referred to as the bezel) to align the orienting lines with the north-south gridlines on the map. Ensure the red orienting arrow on the compass is pointing north on the map and that your map is the right way around.

5. Read the bearing

Read the bearing from the top of the compass housing and refer it back to your estimate to make sure it is what you were expecting. In the illustrated example above, the bearing is 341 degrees, which agrees with the estimation of between 330 and 350 degrees. So to walk between Gwal y Cadno and the stone circle, a bearing of 341 degrees should be followed...

6. Align the compass’s north needle with the orienting arrow

Putting your map to one side, this is where your compass’s red north-facing needle comes into play. Rotate with your compass in hand until the north needle aligns with the red orienting arrow. The direction of travel arrow on your compass will now face the way you intend to go. It’s important to hold the compass horizontally, to allow the magnetic needle to spin freely. Holding it in two hands and locking your elbows to your side is a good way to ensure it stays level.

Walking on a bearing

1. Using terrain features as sighting points

If the visibility is good, there are usually features in the landscape that you can use to help you get from Point A to Point B. For example, when you sight along the direction of travel arrow (see image above) and it’s pointing towards a fixed object – like a building, a rocky outcrop, or a distant summit – you can walk directly towards this with confidence that you are still heading in the right direction.

These sighting points become checkpoints along your route. Objects in the middle distance are better than those that are far away for two reasons. Firstly, they make for easy-to-reach checkpoints on your way to your objective. Secondly, features like a distant summit could be obscured by cloud as you walk towards them. For obvious reasons, don’t walk on a bearing towards a buzzard or a sheep; these don’t fall into the category of fixed objects.

2. Using a friend as a sighting point

If visibility is really poor and you can’t use features in the landscape, you can use your buddy as a sighting point. Show them the bearing (even better if they’ve got their own compass too), ask them to walk ahead until they reach the edge of your visibility and tell them to stop. Check they are still in line with the direction of travel arrow on your compass – ask them to step to the right or left to get back in line if they’re not – and then walk forward to join them. You can then repeat this process, which ensures you stay on your bearing.

3. Walking with the compass set

If you’re alone and there’s very little visibility, you’re going to have to walk with the compass set. This means walking with the compass held out in front of your eyes, following the direction of travel arrow and making sure the red north-facing needle stays within the red north arrow. It’s quite rare that visibility is so poor that you can’t identify at least something as a sighting point, but every now and again this technique will have to be deployed.

4. Advanced techniques

It’s inevitable when walking on a bearing that you will meet the occasional obstacle that you can’t (or don’t want to) walk over, such as a bog or a rocky outcrop. This isn’t an issue If you are walking towards a clear object that you’ve identified as a sighting point. You can simply walk around the obstruction and continue to the sighting point, before taking another look at your compass to identify the next checkpoint on your bearing.

In poor visibility, this can be more of an issue. One way to get around the obstruction while making sure you stay on your bearing is to ‘box’ around it. Let’s say there’s a craggy outcrop that you can go over. If you turn 90 degrees to the right and walk for ten paces; turn 90 degrees to the left and walk another ten paces; and turn 90 degrees to the left again and walk for ten paces; before finally turning 90 degrees back to the right you should be back on your bearing and around the obstacle.
