Sgairneach Mhòr lies to the west of the A9 road in area of high ground which was historically called the Druim Uachdair (the ridge of the upper ground). It is a Munro and a Marilyn with a height of 991 metres (3251 feet). The hill is well seen from the Pass of Drumochter showing off its impressive north facing corrie Coire Creagach which holds snow well into the spring. This notable rocky corrie gives the mountain its name which translates from the Gaelic as Big Rocky Hillside and this underlines the fact that Sgairneach Mhòr is the only hill in the group with any significant stony areas on its surface and makes it the most visually striking of the Drumochter hills.
