To the SW A' Mharconaich links to the adjacent Munro of Beinn Udlamain, again following the fence posts for four km across undulating ground with little loss of height. This area is often teeming with deer being part of the Dalnaspidal deer forest. 2.5 km to the north is another Munro, Geal-chàrn which is reached by descending to a height of 739 metres and traversing around the head of Coire Fhar. Drainage from A' Mharconaich reaches the east coast of Scotland but is divided by the Pass of Drumochter, either going north to join the River Spey or south to meet the River Tay.
