Torridon is a spectacular area in the North West Highlands  dominated by lofty individual mountains of Torridonian sandstone. Torridonian sandstone is of extreme age, 700 to 1000 million years and the mountains consists of level beds of coarse red and brown sandstones, believed to have been upwards of 10km thick before the many hundreds of million years of weathering and many ice ages reduced them to the separate monoliths, barely one kilometre high, that exist today. Many are capped with quartzite and some such as Ben Eighe are predominately formed from quartzite For more authoritive information, reference to a geology field guide is recommended. Some of the mountains are challenging to climb, particularly in winter. They are definitely among the finest mountains in Britain. The Torridonian extend into Assynt, where the are even more separate and, although more diminutive, are no less impressive. The eastern edge of Torridon is bounded by Loch Maree and the area on the other side is Letterewe and beyond, a large tract of wild country described as the Fisherfield ‘Wilderness’. An  area of very rugged hills and long lochs without public road access. It contains what is alleged to be Scotland’s most remote mountain – à Mhaighdean, Gaelic for the Maiden.
