Its outflow, Allt an Dubh-loch, empties into Loch Muick approximately to the southeast near the royal lodge Glas-allt-Shiel. To the southeast of the loch is the Munro Broad Cairn. To the northwest the ground slopes steeply up to CÃÂ rn a' Coire Boidheach and Lochnagar. To the west is Cairn Bannoch and over a high col to the southwest lies Loch Callater.
