Beinn Odhar is part of the Auch Corbetts, a group of five Corbetts which can be climbed in a single days walk from the hamlet of Auch (grid reference ) on the A82. This is a rare situation as the Corbetts are usually difficult to combine in any number and the opportunity to climb five in a natural round is unique. The hills name translates from the Gaelic language as Dun coloured mountain, this alludes to the brownish-grey colour of the heather and grass on the hill. Irvine Butterfield points out that the name is a little insipid given the hills steep slopes and distinctive shape.
