Rannoch Moor is an expanse of around 50 square miles (130 km2) of boggy moorland to the west of Loch Rannoch in Scotland, where it extends from and into westerly Perth and Kinross, northerly Lochaber, and the area of Highland Scotland toward its south-west, northern Argyll and Bute. Rannoch Moor is designated a Site of Special Scientific Interest (SSSI) and a Special Area of Conservation. Much of the western part of the moor lies within the Ben Nevis and Glen Coe National Scenic Area, one of 40 such areas in Scotland.
Glen Roy in the Lochaber area of the Highlands of Scotland is a glen noted for the geological phenomenon of three loch terraces known as the Parallel Roads of Glen Roy. The terraces formed along the shorelines of an ancient ice-dammed loch that existed during a brief period of climatic deterioration, during a much longer period of deglaciation, subsequent to the last main ice age. From a distance they resemble man-made roads running along the side of the glen, hence the name. Much of the glen is designated as a national nature reserve.
