Torridon is recognised as both as a glen and as a region. As a glen it extends from the village of Kinlochewe in the east to Shieldaig on the shores of Upper Loch Torridon on the west coast and best known by mountaineers and walkers for the trinity of fine mountains on its northern flanks, namely Beinn Alligin, 986 metres (3,235 ft), Liathach, 1,055 metres (3,461 ft), and Beinn Eighe, 1,010 metres (3,310 ft). However, as a region its influence extends much further and extends to the Coulin group of mountains to the south of Glen Torridon, to Slioch on the shores of Loch Maree and also the group of hills north of Kinlochewe and south of Gairloch.
The Torridon area is widely acknowledged as having some of the most dramatic mountain scenery in the whole of the British Isles. And that has much to do with its geology. The mountains here are built of Torridonian sandstone set on a plinth of Lewisian gneiss and crowned with white Cambrian quartzite. Over time the sandstone has become eroded to produce the unique characteristics of the Torridon mountains. Each mountain sits very much apart from the next and has steep terraced sides and broken, pinnacled summit crests and riven with steep gullies.
