For VFR navigation, you should make a note from the charts of what will be visible around your waypoints, and write that down in the directions you (or others) will follow. Make a note of the direction and distance (which can be used to calculate expected time for a leg, based on speed) and anything visible that will help orient the pilot.
Example: “follow the river southwest until you reach the ocean, then follow the coast northwest about five NM until you see a small airport”.
Take a look at the “bush trips” for good examples of detailed step-by-step VFR directions.
