Hiking is the preferred term, in Canada and the United States, 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 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, along with rambling (a slightly old-fashioned term), hillwalking, and fell walking.
In the United States, Canada, the Republic of Ireland, and United Kingdom, hiking means walking outdoors on a trail, or off trail, for recreational purposes. A day hike refers to a hike that can be completed in a single day. However, in the United Kingdom, the word walking is also used, as well as rambling, while walking in mountainous areas is called hillwalking. In Northern England, Including the Lake District and Yorkshire Dales, fellwalking describes hill or mountain walks, as fell is the common word for both features there.

Hiking sometimes involves bushwhacking and is sometimes referred to as such. This specifically refers to difficult walking through dense forest, undergrowth, or bushes, where forward progress requires pushing vegetation aside. In extreme cases of bushwhacking, where the vegetation is so dense that human passage is impeded, a machete is used to clear a pathway. The Australian term bushwalking refers to both on and off-trail hiking.

Common terms for hiking used by New Zealanders are tramping , walking or bushwalking. Trekking is the preferred word used to describe multi-day hiking in the mountainous regions of India, Pakistan, Nepal, North America, South America, Iran and in the highlands of East Africa. Hiking a long-distance trail from end-to-end is also referred to as trekking and as thru-hiking in some places. In North America, multi-day hikes, usually with camping, are referred to as backpacking.
Another famous early exponent of walking for pleasure, was the English poet William Wordsworth. In 1790 he embarked on an extended tour of France, Switzerland, and Germany, a journey subsequently recorded in his long autobiographical poem The Prelude (1850). His famous poem Tintern Abbey was inspired by a visit to the Wye Valley made during a walking tour of Wales in 1798 with his sister Dorothy Wordsworth. Wordsworth’s friend Coleridge was another keen walker and in the autumn of 1799, he and Wordsworth undertook a three weeks tour of the Lake District. John Keats, who belonged to the next generation of Romantic poets began, in June 1818, a walking tour of Scotland, Ireland, and the Lake District with his friend Charles Armitage Brown.

More and more people undertook walking tours through the 19th-century, of which the most famous is probably Robert Louis Stevenson’s journey through the CĂ©vennes in France with a donkey, recorded in his Travels with a Donkey (1879). Stevenson also published in 1876 his famous essay “Walking Tours”. The subgenre of travel writing produced many classics in the subsequent 20th-century. An early American example of a book that describes an extended walking tour is naturalist John Muir’s A Thousand Mile Walk to the Gulf (1916), a posthumous published account of a long botanizing walk, undertaken in 1867.
