This describes the main features of the climate of Northern Scotland, comprising Highland Region, the Western Isles, Orkney and Shetland. The principal mainland geographic features comprise the Grampian Mountains and the northern Highlands, which rise steeply from the glens and fjord-like sea lochs. These mountainous areas include the Great Glen, running from Fort William north-eastwards to Inverness and containing Loch Ness. The region therefore has extensive areas of high ground and includes the highest point in the UK - Ben Nevis (1344 metres), near Fort William. There is little urban development, the main towns being Inverness, Fort William, Wick, Kirkwall (Orkney) and Lerwick (Shetland).
