What are the ways you can navigate when you don't have a compass or a GPS? For example how can you tell which way is north.

If you look at the current time, and imagine yourself in the center a big analog watch, just place your shadow on the location of the hour's hand. Then imagine the location of the 12 o'clock hand, and exactly in the middle of the angle between those two hands is the north.

Be sure to ignore daylight saving time (As the time your hand watch is showing during daylight saving is not the "real" astronomical time), and also don't ignore the minutes (so at 15:20 the hand is a 1/3 of a way further on, between 15 and 16).

I also don't know how it works in the southern hemisphere (It might point directly south? I'm not sure - anyone wants to try it out?).

You can also just use a stick to create the shadow for the hour's hand. But using your own shadow makes for a nice trick.

1Please note that there are tricky timezones! Daylight saving is not the only trap, some time zones have nothing to do with ideal distribution - e.g. complete China or Greenland are one timezone, resulting in differences up to three hours, which would be 90 degrees...Paul Paulsen 2014-07-21T15:25:13.360

4This trick is mentioned often, but it's a bit over-complicated for what is really a very simple idea. In the northern hemisphere the sun is east at 6am, south at noon and west at 6pm.

You can forget about this technique for getting a very accurate direction anyway; and that idea is sufficent to get a rough idea of direction. For example if it's 3pm, then the sun is (roughly) south-west.

This is reversed if you're in the south hemisphere and "it's complicated" if you're between the tropical circles. – Agrajag 2015-01-30T09:38:03.773

2don't get it, when I imagine the analog clock, where do the numbers go?Michael Durrant 2012-04-19T02:46:09.580

2Put the short clock hand ("hours") right where your shadow is pointing. From this, you can imagine where 12 o'clock is. For example, if now it's 16:30 and you put the short hand on your shadow, the 12 o'clock hand would be 135 degrees to your left. That means the north is 67.5 degrees to your left.Noam Gal 2012-05-17T10:03:01.173

Carry a clock or carry immagination ;P I carry an analog clock. I point the hour arrow at the sun and know south is approximately to the middle of that and 12o'clock. There are many factors to consider if one is to estimate the accuracy of this method.Vorac 2012-06-01T09:03:35.333

unfortunately - in the age of digital, this won't work too well.HorusKol 2012-01-25T10:02:07.150

21You don't actually need an analog clock. Just the ability to imagine one on the ground around you, and your shadow as the big hand. Maybe even imagining an analog clock is getting harder these days...Noam Gal 2012-01-25T12:22:33.483

I like this. However, I don't think you need to count the minutes. This is going to be crude enough that the difference in minutes is likely to be less than your margin of error. Much, much less if you're like me.Aaron 2017-04-27T21:58:41.547

North and south will be in opposite directions in northern and southern hemispheres.Jani Hyytiäinen 2017-05-03T09:03:37.030

Some type of visual representation would really help explain this. Or a reference. But this is a good tool to know.manoftheson 2013-01-19T02:16:35.750

There seems to be a fixation with North in navigation. Step back to the basic purpose, why do we navigate? We navigate to get to somewhere or to find our way back. Knowing north is just one method of doing such. So predicating navigation on knowing which way is north is unnecessary. North isn't the goal, it's a reference for finding what you really want.

There are two different types of navigation:

  1. Finding our way to something new.
  2. Finding our way back.

I never even touched a map or compass until I was in my 30s and I grew up hiking. This is how I learned to navigate. To quantify where this works, 99% of my outdoors time has been off trail, with no map, in the southeastern US.

I'm going to focus on #2 first, since finding your way back home (or to car) is more critical than finding that waterfall (or lookout, or whatever).

  • Look around when hiking, don't just watch the ground. Note unique features and commit them to memory.
  • Stop periodically and look back. Look over your shoulder a lot. The trail or way will look different on the way back than on the way in. This will also help you spot angling forks that can only be seen from one direction.
  • If you are off trail, with no distinguishing features, leave some clues. Not trash. In deciduous forest, disturbing the leaves works. Breaking small green branches works and causes minimal harm, but don't go overzealous with it. Leave marks that indicate the direction to the previous mark when possible.
  • Take it slow, making sure you absorb the features.
  • Learn to walk a straight line. It takes time, but you can learn to hold a bearing, even in uneven terrain. This can help when you generally know "the highway is that way".
  • If you feel lost, don't panic. Flag your spot in a very visible way. Slowly range out from that spot, but keeping your flag in sight until you see a feature or mark you recognized.

It's really that simple. Don't go on a 20-mile excursion your first time out. Your first several times in the woods should, if possible, be small acreage where if you walk in any direction for an hour you'll hit a road or known trail.

What about finding something new? When I hike a new trail, I browse the Internet until I find someone who has taken the time to write directions that don't require a map and compass. I contribute corrections as I find them. Sometimes I never find the thing I left to see, but find something else in the process. Sometimes I find it hours late, but it's a fun trip.

I sometimes wonder if trails handicap learning to navigate. Many people end up knowing little about traveling in the woods but following a trail or staring at a map/gps.

And don't get me wrong, I can use a map now and a high quality Topo map is awesome. But you certainly don't need to know North avoid getting lost (caveat here that I'm sure it's different in some deserts).

+1 for impressive skill. I nearly never hiked without a map, but maybe I will try to get some training as you suggested.Paul Paulsen 2014-07-21T15:30:53.710

10+1 for "Stop periodically and look back". This was one of two things they told us about caves - the other was, of course, carry a spare flashlight.Vorac 2012-06-01T09:09:04.997

6In the desert there usually no prominent features around you (like your caveat mentions), and everything withing a few miles looks exactly the same. How you navigate is watch the mountains that are 30 to 60 miles off. Before you start stand facing your car (or the road) and take notice of how far you have to turn or twist your neck to look or arms to point at the mountains. If you continue to update that as you hike, you can always find your way back. Note, this wouldn't work in the Dunes, but nothing works there.MaskedPlant 2012-06-10T14:49:09.297

Is this for open terrain, where we can watch far-away features easily as long as the weather is clear, or for dense forest? Why would you choose to use directions found on the internet over a (topographic) map?gerrit 2016-04-18T16:34:56.157

Topographical maps only tell a (very small) part of the story. The features of the landscape go far beyond elevation. Also, I already qualified that in the answer -- "To quantify where this works, 99% of my outdoors time has been off trail, with no map, in the southeastern US." ie - mostly dense forest.Russell Steen 2016-04-18T16:44:35.410

1+1 - I agree with all of those points. But if you do have a realistic method of finding where north is, that can never be a bad thing.berry120 2012-02-01T00:18:09.933

@berry120 -- I absolutely agree that finding North isn't bad :)Russell Steen 2012-02-01T00:59:46.910

If there's a stick around and enough sunlight, I've found the stick method surprisingly accurate:

  1. Find a straight stick, around 2 feet long (length isn't that important) and plant it straight in the ground.
  2. Mark the end of the stick's shadow, perhaps with another short stick.
  3. Wait for about 15 minutes then repeat step 2.
  4. Draw a line between the two ends you marked in step 2, from the first marker to the second. This will produce a line that points from west to east (where west is in the direction of the first mark you made, east towards the second.)
  5. Draw a line perpendicular to the one you've just drawn and that will point north to south.

I've used this a few times just for fun, never needed to in an emergency situation - but it's surprisingly accurate for such a primitive method, usually only a few degrees off.

See here for a video explanation.

1Does it work only in the northern hemisphere? I imagine in the southern it would be from east to west instead, but not sure...Paul Paulsen 2014-07-21T15:26:59.653

2That won't work in England for lack of sunshine.gerrit 2016-04-18T16:31:56.277

3@PaulPaulsen In the southern hemisphere, the first mark will still be the west end of the line (because the sun goes east-to-west in both hemispheres); the shadow will just be south of the stick instead of north of it.Dan Henderson 2016-04-18T22:39:01.993

@DanHenderson thanks for the clarification. of course you are right.Paul Paulsen 2016-04-23T12:32:33.190

Basic celestial navigation:

In the northern hemisphere, the star Polaris indicates north.

In the southern hemisphere, you can use the Southern Cross, see Finding the south celestial pole.

Southern Cross navigation how-to: http://www.teara.govt.nz/en/southern-cross/2/3

Danubian Sailor 2012-06-11T12:12:18.127

You are wrong! Southern cross is not an analogy of the Polaris in the southern hemisphere! THe Southern Cross is rotating and need not necessarily point to the south.Tomas 2012-01-27T23:11:26.577

1The Southern Cross can still be used to point your way south. It's not as quick and easy as Polaris (which doesn't lie at true north, it's just a whole lot closer), but it still works.MBraedley 2012-02-01T19:45:47.043

If it's early morning, you'll note that the sun rises in the east. It additionally sets in the West. Normally, more plant-life can be found on the east side of a ridge (I don't have a source for this, I'm sure someone else can be more helpful) as it more fully receives light.

Personally, I navigate almost exclusively by features and carry a contour map with me of the area. I also memorize some prominent features before heading out as a safety precaution. Remember to always map out your route and tell a friend where you're going!

1Navigating by features is very useful - until the fog moves inHorusKol 2012-01-25T10:03:04.027

1Yes, well. A sense of direction tends to fix that problem :) As does backtracking, not panicking, etc.A.A. Grapsas 2012-01-25T23:56:30.017

true - but to a novice that doesn't know any better, your answer can kind of read like "leave the compass at home"HorusKol 2012-01-26T01:31:49.087

2Novices should be in a group with experienced people, that's the best advice that can be given.A.A. Grapsas 2012-01-31T21:22:44.147

The distribution of sun east / west should be pretty close to the same. In the northern hemisphere, the south side of areas gets more sun due to the sun being more to the south (perpendicular to the equator).

This doesn't necessarily translate into there being more vegetation on the south side of ridges though, it depends on the environment. Southern California for instance will typically have less vegetation on the south side of a slope due to the increased heat and very low level of moisture. In less arid areas, you can see more vegetation on the south slope because they are not starved for water and they have more sunlight than the north slope will.

To sum that up, it's not safe to determine north or south based solely on presence of vegetation. You have to know your environment and what the effects of additional sunlight will have on the area.

When I go off-trail into the woods, I bring a topographic map, compass and GPS with me; of the three, the one I use least is the compass and the one I use most is the map, because I have learned to read the terrain and match it to the map.

Even if you know which way is north, that may be very little help in knowing where you are, how to get where you want to go, or how to get there safely (e.g. avoiding ravines, cliffs, and other natural hazards).

Learn to read a topographic map and it will serve you very well.

Depending on the terrain, a map is often very usable even without a compass or a GPS. If the terrain is anything-but-flat you can generally use the contours of the terrain to orient the map correctly. "Walk down this valley until it branches, then head for the mountain aproximately 30 degrees left." doesn't require a compass.

Learn to read contour-lines on maps, so that you're able to visualize the terrain from the map. Follow lead-lines whenever practical. Rivers, ridges, lakes, treelines, coastlines, powerlines or (obviously) roads are all candidates.

  • Jason S's "use the map" or / and Russell Steen's "use landmarks"
  • Noam Gal's and berry120's "use the sun" (1)
  • Graham's "use the stars"
  • use rivers - rivers provide water, animals, human-inhabited places, never go in circles and always flow in a consistent direction (this is kind of "use landmarks")
  • climb up high - 1. find a naked hilltop 2. climb it 3. you can now see far away and are also easier to be seen
  • use the moon - for example here this is explained

(1) I was recently looking to measure how accurate my compass is. After some discussions, I was persuaded that the sun is very inaccurate (maybe tens of degrees off when measured with a watch). Well, It is the most easily accessed orientation point, so nevertheless I use it most often of all sources (even when I carry a compass).

I want to suggest a couple of books I really like:

These books are not about quick tips and tricks. These books are filled with stories, history and a lot of nuances that will take a lot of time to actually master. These books are great for anyone who is really serious about the art of navigation (which entails getting closer to nature, noticing more,...). It's great if you're really serious about navigation and the outdoors in general or if you just want a nice read, but as I said before, don't expect a tips&tricks format.

1I will probably have a look at these books, but this would be a much better answer if you could provide a couple of examples quotes...Rory Alsop 2013-01-21T08:18:26.730

@RoryAlsop I'm aware of that, however, these books just can't be quoted without feeling like a quote miner. You just have to hear the whole story, that's why I didn't include any quotes. You can always read the first chapter on Amazon though.Ben 2013-01-21T18:53:11.470
