Rannoch Moor is an expanse of around 50 square miles (130 km2) of boggy moorland to the west of Loch Rannoch in Scotland, from where it extends 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.
