With 5 stages courses can provide skills and qualifications to potential leaders.
Firstly, familiarise yourself with it… Things to look for include scale, contour intervals, colours, start point of your journey, which way is north.
Put your map into an A4 size mapcase, with the side up being the area to be walked, and the reverse side showing the route card.
A route card is a sheet detailing the walk you have planned to do, including grid references, steepness/elevation, estimated times & distances and other relevant information.
This is an example of a route card, other information it can contain includes the height gained and lost during each leg of the route, estimated and actual times.

Before you start walking, locate your position on the map.
Always know where north is on your map, and always point your map north!
Once you have found that, you are on the way!
A grid reference (GR) is a set of numbers (usually 6) that will indicate a point on a map. A six figure GR looks like this 574 678. THE FIRST 3 NUMBERS indicate how far EAST the point is on the map, and THE SECOND 3 NUMBERS indicate how far NORTH the point is on the map. GRs are always relative to the map you are using, so always quote the map you got it from.
There are straight lines drawn on South Australian (and most Australian) topographic maps called Grid Lines. These lines are 1km apart, and about 1.5 km from corner to corner. These lines are numbered along the bottom and up the side of the map and are called grid numbers. They range from 00 to 99. The grid numbers along the bottom are called eastings, because the numbers increase as you go east, and up the sides; northings. This is for the same reason. For all references, always read eastings first.
Divide the 1 km space between gridlines into 10 lots of 100m and number them 1 to 0. So, a six figure grid reference will be split into 2 groups of 3 numbers.
Contours are drawn on a map linking up places of the same height. These lines are at standard intervals (called contour intervals and found on the map legend). South Australian topographic maps are usually 10 m apart, but make sure you check. These lines indicate height above sea level on a map and will tell you how much up and down hill sections your intended days walking will have. Understanding contour lines is ‘the trick’ in improving your navigation. The closer the lines are together, the steeper the terrain is.
A compass is handy in poor visibility, in thick scrub or to confirm where you are. See the illustration for an example. Protractor compasses have a medium sized base plate with easy to read numbers on it. Practice using a compass and understand the variances in “north” (magnetic/grid).
If navigation is an issue, you are not alone. Think about improving your skills. Learning navigation (getting rid of that lost feeling) is excellent for your bush walking confidence and competence.
Bushwalking Leadership SA offers courses in navigation, bushwalking skills and leadership for beginners to experienced bushwalkers.
Other places to consider could be orienteering or rogaining clubs, or bushwalking groups.
Natmap put out an excellent booklet that will get you started It is called Map Reading Guide – how to use topographic maps and costs around $4. It comes with a bonus plastic map card. This will help you develop your map reading skills. It is available from outdoor retailers.
Bushwalking Leadership South Australia, in putting this information together, does in no way suggest that this is the ultimate guide and STRONGLY recommends anyone interested in bushwalking to educate themselves in the dangers involved with this activity.
Bushwalking Leadership SA STRONGLY advocates first aid training and recognised outdoor leadership training before leading groups of any sort of bushwalking.
