ago. The linear geological feature of Moine Thrust Belt runs northeast across the area from near Kyle of Lochalsh. The area was heavily glaciated during the ice age, with all but the highest peaks being covered by glaciers, leading to the steep-sided glens and deep sea lochs that characterise the area today. Geography Wester Ross is well known for its spectacular mountain scenery, especially the Torridon Hills which includes such peaks as Beinn Eighe and Liathach. Although many peaks in the Northwest highlands exhibit Torridonian geology, the Torridon Hills are generally considered only to be those in the Torridon Forest to the north of Glen Torridon: the Munros of Liathach, Beinn Eighe, and Beinn Alligin; and the Corbetts of Beinn Dearg, Baosbheinn and Beinn an Eoin. Other notable "Torridonian" peaks in Wester Ross include An Teallach and Slioch, in the Dundonnell and Fisherfield Forest in the north of the area, and the hills of the Coulin Forest between Glen Torridon and Strathcarron. Torridonian hills exhibit some of the most dramatic mountain scenery in the British Isles, surpassed in grandeur probably only by the Cuillin of Skye. The hills sit apart from each other, and are often likened to castles. They have steep terraced sides, and broken summit crests, riven into many pinnacles. There are many steep gullies running down the terraced sides. The summit ridges provide excellent scrambling, and are popular with hill walkers and mountaineers. However, like many ridge routes, there are few escape points, so once committed, the scrambler or hillwalker must complete the entire ridge before descent. Under winter conditions, many walking routes in Wester Ross become serious expeditions. In contrast to the isolated Torridonian peaks that characterise much of Wester Ross, the mountains of Kintail in the south of the area take the form of peaks linked by ridges that rise steeply from narrow glens and the sea. Most of the major roads in the area radiate out from the more populated areas of Easter Ross, and link the settlements on the western coast to Inverness. Less major roads link these east–west routes to form a north–south route along the coast between Kyle of Lochalsh and Ullapool. This route has been marketed to tourists as the Wester Ross Coastal Trail, and also forms part of the North Coast 500 tourist route. The only railway line in Wester Ross is the Kyle of Lochalsh line, which is
