The most straightforward route to the summit Mullach Glas is the 10-kilometre 4-5 hour roundtrip route from the pass at Máméan 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).
