Orienteering is navigation across terrain using a map and, when needed, a compass. Orienteering skills are useful to outdoor enthusiasts. In deserts and mountains, these skills can and often do save lives, as well as making outdoor adventures less stressful and more enjoyable.
The orienteering skills needed while hiking differ substantially from those needed in usual orienteering competitions. What you learn at any orienteering club or orienteering event is certainly useful, but you should also train orienteering in a hiking context and get some advice specific for hiking in terrain resembling that which is ahead, before going for demanding wilderness backpacking.
The biggest difference between typical competitive orienteering and wilderness orienteering is the quality of maps and the distances. In the wilderness you will – to a much bigger extent – have to infer the characteristics of any terrain from hints on the map. You will also have to decide where minor streams can be crossed, where to find good water and where to put your tent, in addition to choosing a good path for advancing. On the other hand, you are seldom in a hurry and you need much less precision.
Orienteering is a fun activity for travellers. Avid orienteers have been known to plan all their vacations (and work related travel too) around opportunities to go orienteering. See the article on New Mexico for information about orienteering there.
There may very well be a hiking club where you live. They often arrange events also for inexperienced non-members and can help you get going.
Just using a map and compass at any hike or walk in the nature will teach you much. Tips on what to look for (read: advice from an orienteer or experienced hiker) will make you learn much quicker.
While satellite navigators have become affordable and easy to carry and use, the necessity of traditional orienteering skills have in no way disappeared. You need orienteering skills to judge the information offered by the device and converting it to a real life route (and to get along would the device fail).
In many cases the device gives you an exact position and the direction to your next waypoint. But the shortest path is seldom ideal, sometimes even dangerous. Having made a typing mistake (or prematurely assumed your map uses WGS84 coordinates) you may be directed to the middle of nowhere. And in the backcountry you should use batteries sparingly, which means having the device turned off most of the time.
When abroad, you will probably use maps that differ significantly from those at home. Learn the most important symbols, colours, hight between contour lines et cetera, check magnetic declination and the coordinate system (which may have to be used at least when coordinating with GPS devices and to get help) and try to find out how reliable the information on the map is.
Different terrain and kind of orienteering have different requirements on the map. While maps used in orienteering competitions should lead you some metres from a certain small rock, when hiking in open terrain the map getting you a few hundred metres – or even a few kilometres – from the destination might be enough for you to find it. While orienteering maps are often in the scale 1:5,000, outdoor maps may be e.g. 1:25,000, 1:50,000 or even 1:100,000. With smaller scale you need fewer sheets, but in difficult terrain you may need the big scale ones. Depending on terrain different features may be the key for finding and following a good route. Topography (hills, valleys and mountains) is nearly always important, but e.g. water sources, character of swamps, roughness of terrain and denseness of forest are more important in some regions.
Where resources for high quality map making are not available, much coarser maps, e.g. with only mountains, lakes and infrastructure decently marked, may have to be used (as in most backcountry before the time of cheap aviation and satellites). With such maps you have to be able to make sound assumptions on the terrain at your route and find features you will surely recognize. Unless you are confident about your skills, having a guide or only following well maintained trails is a safer option.
In lack of a compass, the sun, moon or stars can be used to find cardinal directions.
For using the sun, you should know it is in the east in the morning (6 AM) and in the west in the evening (6PM), and where it is at noon (north of the tropics: in the south, south of them: in the north). Interpolate as needed, and remember this is sun time, not standard time (so in Paris, subtract an hour or two from what your watch shows).
On the northern hemisphere you should know how to find the Pole Star, which is constantly nearly exactly above geographic north (near the Equator the Pole Star is low, near the North Pole near zenith, so probably difficult to use in both cases). On the southern hemisphere you have the Crux, but it is quite far from geographic south. You can get a point farther south by extrapolating a line between the stars. If you know when other stars are in certain directions, you can use them too.
Those not confused by geometry can also use the moon: as the moon gets its light from the sun, you could estimate from where the sun beams are coming. Then use the location of the sun to get the compass points. If you face the full moon, you have the sun behind your back, if you face a first quarter half-moon on the northern hemisphere you have the sun to your right. If you are north of the tropics and it is midnight, the sun, in turn, is in the north, and you are turned to the south or the west, respectively.
(South of the tropics, the directions are kind of reversed: the sun still rises in the east, but it is to the north at noon. In the tropics, the situation is more confused, as the noon sun near the equator is in the north in the northern hemisphere summer and in the south in the southern hemisphere summer; in Midsummer and Midwinter this is true for all the tropics, while in mid-spring and mid-autumn the directions are like on the rest of the respective hemispheres.)
If you cannot figure out where the sun, the moon or the stars you are seeing should be, you can still use them to keep an approximate direction. They will move only 15° an hour (360°/24h), so for any short distance they will more or less stay fixed. Keep the celestial body at the same point in your field of view, or your shadow pointing in the same direction. You can use a steady wind in a similar manner: if it's on your right cheek, keep it there. The wind is a bit unreliable; to trust it you need to be able to recognise it shifting or know it won't.
There are also signs on ground level, such as ant nests, moss and the shape of lonely trees, which are directed approximately towards or away from the midday sun. Using them requires some more training and the signs vary between climate zones.
For keeping a direction in fog or snowfall in open terrain one can form a line: the one walking last will see when the one walking first deviates from the course, as those walking in the middle are still walking on the previous course. Practise this both to get it work and to get a feeling for how accurately you can keep the course; you will walk in circles, but very much larger circles than when trying to keep a course alone.
Safety in the natural environment is an important goal of orienteering training. Essential skills taught and developed through organized orienteering events, which apply also to many other outdoor activities, include the following:
