Loch Scridain extends inland as far as the island's only Munro and extinct volcano, Ben More, a large massif on the Ardmeanach peninsula to the north; the imposing Bearraich hill overlooks the mouth of the loch. To the south is the Ross of Mull, the longest peninsula on Mull, that reaches past the sea loch boundary into the Atlantic. Near the head of Loch Scridain is the Aird of Kinloch, a small peninsula that almost separates the main loch from the small inner sea loch, Loch Beg. Loch Beg is fed by the River Coladoir.
