Walk: Mad Meggy & her ugly sisters

Highland | Laggan | Full day walk | ★★★★

[Coire Ardair, Creag Meagaidh]

Creag Meagaidh (which translates as the rather unflattering boggy crag) is the highest summit in a sprawling massif slightly adrift of the Monadliath range above Loch Laggan. This circuit also takes in a further pair of less memorable Munro peaks (and several other minor summits) overlooking the north side of the captivating glen cut by the Allt Coire Ardair. The higher terrain is a vast plateau dotted with a few curious, rocky clefts; the contrast with the regenerating forest and burbling burn at glen level couldn't be greater. But the real highlight of the day has to be Coire Ardair: a sparkling lochan encircled by mighty crags adored by ice climbers in winter and by golden eagles year-round.
