Beinn Achaladair's other significant corrie is Corrie Achaladair which stands to the south of the mountain and forms a col with the adjoining Munro of Beinn an Dotaidh. The mountain's steep northern and western slopes are rocky higher up before becoming grassy as they fall to the valley. These grassy slopes are riven with many small streams which drain to the Water of Tulla which drains into Loch Tulla.
