A prominent grassy summit on an elongated ridge in Stirling, Stob Fear-tomhais rises to 771m (2529 feet) at the head of Gleann Dubh, 2 miles (3 km) south of Loch Doine and a similar distance east of Stob Breac in the Loch Lomond and the Trossachs National Park. It qualifies as a Corbett. Although unnamed on Ordnance Survey maps, this mountain is known locally as Surveyor's Peak owing to the triangulation pillar at its summit. Because the name of a neighbouring hill, Ceann na Baintighearna, was being used and causing confusion, the Scottish Mountaineering Club rather artificially translated Surveyor's Peak into Gaelic for their guidebook, to give Stob Fear-tomhais.
Streams rising on its slopes flow west to the Invernenty Burn, northeast to become Allt Fathan Glinne and southeast into the Allt a' Ghlinne Dhuibh.
