Orienteering in the countryside is quite different from orienteering in a park. In a forest, a dip, a turn or even a stray fog may cause one to lose sight of the landmark one has been steering by, and one tree can look very much like another.
與城市公園中的定向規劃不同，森林中的定向比賽多在深山野林中舉行，一個轉身或者一陣濃霧飄過，原來在前方指路的高山就可能不見了，無論怎麼繞，周圍的大樹好像長得都一樣，深陷其中的人始終在原點打轉，越來越心慌腳軟。
