An Teallach is a complex mountain massif, with ten distinct summits over 3,000 feet (914.4 m). From 1891 to 1981, only the highest of these, Bidean a' Ghlas Thuill, had the status of a Munro - a separate mountain over 3,000 feet. In 1981 the Scottish Mountaineering Club granted Munro status to Sgùrr Fiona, in recognition of its considerable topographic prominence (142 m) and distinct nature. The complete list of Munros and Tops (subsidiary summits appearing on Munro's Tables) is now as follows:
