The NE summit is regarded as the highest point and this has been confirmed by an Abney Level survey which found the SW top, named Bruach nan Iomairean, to be a few metres lower.

The less well defined eastern ridge descends steeply from Bruach nan Iomairean to a col with a height of approximately 655 metres which links to the hill the Boar of Badenoch also known as An Torc.

[7] To the SW A' Mharconaich links to the adjacent Munro of Beinn Udlamain, again following the fence posts for four km across undulating ground with little loss of height.

One route starts on the A9 at the top of the Pass of Drumochter at grid reference NN632755 and goes up Coire Dhomhain for just over a kilometre and then ascending NW to the col between A' Mharconaich and the Boar of Badenoch from where the line of fence posts is followed steeply to the summit ridge.

An alternative start is at Balsporran cottages (NN627791), and offers a direct ascent up the NE ridge or a longer walk which takes in the adjoining Munro of Geal-chàrn.
