Mullach Fraoch-choire is located south of upper Glen Affric and north of Loch Cluanie at the head of Glenmoriston as the valley continues west to become Glen Shiel and Kintail. The mountain is one of the four Munros on the Cluanie Horseshoe, a crescent of high peaks which also includes nine Munro Tops. It lies on the western arm of the horseshoe which loops around Gleann na Ciche whose burns flow north to the River Affric. West of the horseshoe is a deep glen connecting Cluanie and Affric - south of its watershed is An Caorran Mor with its stream flowing south to Loch Cluanie while to the north Allt a' Chomhlain flows north to the River Affric. Mullach Fraoch-choire has a subsidiary Top on its northeast ridge at . Somewhat beyond the lowest col on its south ridge is Stob Coire na Chràlaig at which is regarded as a subsidiary peak of A' Chràlaig although it is more distant from the latter peak.
