Hiking is the approved term in Canada and the United States, for a long, vigorous walk, usually on trails (footpaths), in the countryside. In contrast, the word walking is used for shorter, particularly urban walks. On the other hand, in the United Kingdom and the Republic of Ireland, the word “walking” is acceptable to describe all forms of walking, whether it is a walk in the park or backpacking in the Alps.
The word hiking is also often used in the UK, rambling (a slightly old-fashioned term), hillwalking, and fell walking (mainly for hillwalking in northern England). The term bushwalking is endemic to Australia, adopted by the Sydney Bush Walkers club in 1927. In New Zealand, a long, vigorous walk or hike is called tramping. It is a popular activity with numerous hiking organizations worldwide, and studies suggest that all forms of walking have health benefits.
