Ben Nevis (/ˈnɛvɪs/ NEV-iss; Scottish Gaelic: Beinn Nibheis, Scottish Gaelic pronunciation: [pe(ɲ) ˈɲivɪʃ]) is the highest mountain in Scotland, the United Kingdom, and the British Isles. Ben Nevis stands at the western end of the Grampian Mountains in the Highland region of Lochaber, close to the town of Fort William. The mountain's name can translate to either "cloudy mountain" or "venomous mountain".
The mountain is a popular destination, attracting an estimated 150,000 visitors a year, around three-quarters of which use the Mountain Track from Glen Nevis. The mountain has hosted a foot race since 1898. The 700-metre (2,300 ft) cliffs of the north face are among the highest in Scotland, providing classic scrambles and rock climbs of all difficulties for climbers and mountaineers. They are also the principal locations in Scotland for ice climbing. The cliffs of the north face can be viewed from the Charles Inglis Clark Memorial Hut, a private alpine hut.
The summit is 1,345 metres (4,413 ft) above sea level and is the highest land in any direction for 739 kilometres (459 miles). The summit is a stony plateau (a felsenmeer). It features a number of monuments and the ruins of an observatory which was continuously staffed between 1883 and 1904. The meteorological data collected during this period is still important for understanding Scottish mountain weather. C. T. R. Wilson was inspired to invent the cloud chamber after a period spent working at the observatory.
