Beinn Udlamain is invariably ascended from the A9 road from near the summit of the Drumochter Pass at grid reference , which gives a starting altitude of 462 metres. From here the direct ascent goes up Coire Dhomhain to its head where the south ridge of the mountain can be followed to the summit. A complete round of all the peaks around Coire Dhomhain can be done from this starting point, including the two already mentioned Munros and the Corbett The Sow of Atholl. The summit of the mountain is marked by a large cairn and wind shelter. The highlight of the view from the summit is to the SW where there is a fine view of a long stretch of Loch Ericht with the Ben Alder massif behind.
