A' Chrois is a mountain located in the Arrochar Alps north west of Arrochar in Argyll, an extremely scenic area which is technically in the highlands although it is within easy reach of the heavily populated areas of Glasgow. A' Chrois stands north of Arrochar at the head of Loch Long and reaches a height of 848 meters (2,782 ft). The mountain forms a ridge starting with Ben Arthur The Cobbler in the south by Ardgartan through Beinn Narnain to A' Chrois in the north by Glen Loin, visible to Loch Lomond.
