Access: Either park at Layby 81 on the northbound side of the A9 at
the summit of Drumochter Pass, or park at Balsporran Cottages.
There is a fine cycle track beside the A9 which connects the two points.
Route: Straightforward terrain throughout: easy short grass or moss on ridges. (In a hurry on this day in order to reach Cannich at a reasonable time.)
Although only a fairly average-sized walk, the route can easily be broken into two parts, each one covering two of the four Munros: Beinn Udlamain and Sgairneach Mhor would be done with both ascent and descent using Layby 81 and the track along Coire Dhomhain, whilst A'Mharconaich and Geal-charn would be done from Balsporran Cottages using their NE ridges.
The route is easily done either clockwise or anti-clockwise. Clockwise might be best when the prevailing SW wind is blowing.
In poor conditions there are many escape routes eastwards down ridges or along valley tracks back to the A9.
Geal-charn has two summit cairns, that to the SW being the higher. A'Mharconaich has two tops, that to the NE now being recognised as the summit.
Sgairneach Mhor can be scaled from the track in Coire Dhomhain using either its NNW ridge or its NE ridge
Conditions: Excellent walking weather: dry, sunny spells, light wind, 18°C initially at Drumochter Pass layby, 20°C by finish.
