The most straightforward route to the summit Corcogemore is the 5-kilometre 2-3 hour roundtrip route from the R336 road, just after Maam Cross, and back; however, because of its positioning on a high ridge of its own small massif, it can also be climbed as an alternative 10-kilometre 4-5 hour route from Corcogemore in the west, across Mullach Glas, to the summit of Binn Mhór, and then finishing down at Máméan (i.e. the route requires two cars).
