This walk is just off the A9 near the summit of Drumochter Pass; it takes in three Munros: Sgairneach Mhor (991M), Beinn Udlamain (1011M) and A’Mharconaich (975M). You should be using OS Explorer Map 393 – Ben Alder, Loch Ericht and Loch Laggan.
Start at layby 81 on the A9. (If you are lucky the Bacon Buttie Van will be there, and I can highly recommend the black pudding bap at £1.50!) To begin the walk, follow the track down the A9 for 800m until you reach a farm gate and the old road. Take the old road for 300m until you reach a fork, here you should bear right passing under the railway.
Follow the right track, as it gradually climbs up Coire Dhomhain, for just over two kilometres until you get to the second new bridge which passes over the Allt Coire Dhomhain. Follow the remains of a Landrover track up the side of Sgairneach Mhor until you reach the shoulder. Once on the shoulder, it is an easy 600m up to the trig point and the remains of a shelter.
At the trig point, take a bearing South West and follow it for 600m; then take another bearing towards the remains of a fence on the shoulder of Beinn Udlamain. The ground initially dips down to 809m before a short ascent to gain the fence line at 860m. Follow the remains of this fence for about 1.2 kilomertres. It is quite an easy ascent to the top of Beinn Udlamain and on a clear day you can get great views of Loch Ericht and Ben Nevis in the distance.
Continue to follow the fence line as it heads North East towards A’Mharconaich. After 1.5 kilometre the path drops down into a cwm at 861m. As you start the ascent up A’Mharconaich, follow the right hand path which, after approx 1km, will take you to the top (975m). This is a grassy knoll marked with a cairn.
If you have time you can reach another munro from this hill, Geal-charn (917m) or, to return to the car, head back to the fence line and follow this down the hill as you zig zag slowly back to the track in Coire Dhomhain. Then follow the track back to the A9 and layby 81.
