Steps
Print or buy the topo map that covers your whole route plus a margin around it. Check the map's date and edition so you know how current the trails are.
Find the contour interval in the map legend, usually printed as a number of feet or meters. Every contour line you cross means that much elevation change.
Look at how close the contour lines sit. Tightly packed lines mean a steep slope, widely spaced lines mean gentle ground, and you can plan your climb around that.
Study the shapes. Closed loops that shrink inward mark a peak, hourglass shapes mark a saddle, and V shapes pointing uphill mark a drainage or gully.
Read the legend for color and symbol meanings. Blue is water, green is vegetation, and brown lines are terrain, while symbols mark trails, roads and buildings.
Check the map scale, such as 1:24,000, and use the scale bar to convert a measured distance on paper into real trail distance.
Match landmarks you can see, like a lake, ridge or trail junction, to the same feature on the map to orient yourself.
Measure your planned route with the scale bar or a piece of string along the trail line to get the distance, then add extra for switchbacks and climbs.
Locate yourself by finding two or three landmarks you can identify and drawing lines from them on the map. Where the lines cross is roughly where you stand.
Tips and common mistakes
Fold the map so only the section you need shows, which makes it easier to read in wind and rain.
Keep the map in a clear plastic bag or map case so sweat and rain do not destroy it.
Check your position at every junction and prominent landmark instead of waiting until you feel lost.
Contour lines never cross, so if two lines seem to meet you are misreading a cliff or overhang symbol.
Questions
Do I really need a paper map if I have a GPS app?
A paper map keeps working when your phone battery dies or you lose signal. Carry it as a backup and know how to read it before you rely on it.
What does a contour interval of 40 feet mean?
Each contour line you cross represents 40 feet of elevation gain or loss. Counting the lines between two points tells you how much climbing is ahead.
How do I find my position without a compass?
Identify two or three landmarks you can see and match them to the map, then draw lines from each. Where the lines cross is your approximate position.
