Beinn Iutharn Mhor is a big Munro lying at the head of Glen Ey. The summit sits at the west end of a craggy summit ridge with spectacularly sharp drops to the north. Beinn Iutharn Mhor has two subsidiary tops (much smaller) Beinn Iutharn Bheag to the SE of the Summit and Mam nan Carn to the SW of the summit, these both add impressive bulk to its southern faces.
Beinn Iutharn Mhor is normally climbed in conjunction with Carn Bhac which is connected to Beinn Iutharn Mhor via a long ridge running north from the eastern end of the main summit ridge. From Carn Bhac you can fully appreciate the north face of Beinn Iutharn Mhor perhaps the best feature of the hill.
Access to the hill is usually via a long walk/cycle in to Altanour Lodge from Inverey to the north. This is on a good path and distance can be covered quickly. From the lodge you can either head NW to take on Carn Bhac first or head SE to tackle Beinn Iutharn Mhor first via its long NE ridge to the summit.
