A bothy is a basic shelter, usually left unlocked and available for anyone to use free of charge. It was also a term for basic accommodation, usually for gardeners or other workers on an estate. Bothies are to be found in remote, mountainous areas of Scotland, Northern England, Ireland and Wales. They are particularly common in the Scottish Highlands but related buildings can be found around the world (e.g., in the Nordic countries, there are wilderness huts). A bothy was also a semi-legal drinking den in the Isle of Lewis. These, such as Bothan Eòrapaidh, were used until recent years as gathering points for local men, and were often situated in an old hut or caravan.
The etymology of the word bothy is uncertain. Suggestions include a relation to both "hut" as in Irish bothán and Scottish Gaelic bothan or bothag.; a corruption of the Welsh term bwthyn, also meaning small cottage; and a derivation from Norse būð, cognate with English booth with a diminutive ending.
Most bothies are ruined buildings which have been restored to a basic standard, providing a windproof and watertight shelter. They vary in size from little more than a large box up to two-storey cottages. They usually have designated sleeping areas, which commonly are either an upstairs room or a raised platform, thus allowing one to keep clear of cold air and draughts at floor height. No bedding, mattresses or blankets are provided. Public access to bothies is either on foot, by bicycle or boat.
Most bothies have a fireplace and are near a natural source of water. A spade may be provided to bury excrement.
