Hiking in Canada and the USA is the preferred term for a long, vigorous walk, usually on trails (footpaths), in the countryside, while the word walking is used for shorter, particularly urban walks. On the other hand in the United Kingdom, and the Republic of Ireland, the term walking is used to describe all forms of walking, whether it is a walk in the park or trekking in the Alps. The word hiking is also sometimes used in the UK, along with rambling, hill walking, and fell walking. 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.
