Hiking is a long, vigorous walk, usually on trails or footpaths in the
countryside. Walking for pleasure developed in Europe during the
eighteenth century. "Hiking" is the preferred term in Canada and the
United States; the term "walking" is used in these regions for shorter,
particularly urban walks. In the United Kingdom and the Republic of
Ireland, the word "walking" describes 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, along with rambling (a slightly old-fashioned
term), hillwalking, and fell walking (a term mostly used for hillwalking
in northern England). The term bushwalking is endemic to Australia,
having been 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.
