Walking is one of the most popular outdoor recreational activities in the United Kingdom, and within England and Wales there is a comprehensive network of rights of way that permits access to the countryside. Furthermore, access to much uncultivated and unenclosed land has opened up since the enactment of the Countryside and Rights of Way Act 2000. In Scotland the ancient tradition of universal access to land was formally codified under the Land Reform (Scotland) Act 2003. In Northern Ireland, however, there are few rights of way, or other access to land. Walking is used in the United Kingdom to describe a range of activity, from a walk in the park to trekking in the Alps. The word "hiking" is used in the UK, but less often than walking; the word rambling (akin to roam) is also used, and the main organisation that supports walking is called The Ramblers. Walking in mountainous areas in the UK is called hillwalking, or in Northern England, including the Lake District and Yorkshire Dales, fellwalking, from the dialect word fell for high, uncultivated land. Mountain walking can sometimes involve scrambling. The idea of undertaking a walk through the countryside for pleasure developed in the 18th century, and arose because of changing attitudes to the landscape and nature, associated with the Romantic movement. In earlier times walking generally indicated poverty and was also associated with vagrancy. Thomas West, an English priest, popularised the idea of walking for pleasure in his guide to the Lake District of 1778. In the introduction he wrote that he aimed to encourage the taste of visiting the lakes by furnishing the traveller with a Guide; and for that purpose, the writer has here collected and laid before him, all the select stations and points of view, noticed by those authors who have last made the tour of the lakes, verified by his own repeated observations. To this end he included various "stations" or viewpoints around the lakes, from which tourists would be encouraged to appreciate the views in terms of their aesthetic qualities.
