I walked over to the finest viewpoints looking down to Loch A'an. By now Ben Macdui was now in thick cloud and the sun was getting blanked out. I headed back across the plateau via Feithe Buidhe. Up to this point I had only seen a few folk, from a distance. Nearly all my route up to this point had been off a path. At 3.10pm I spotted a few folk wearing shorts at Lochan Buidhe, heading up on the Ben Macdui path. I was feeling slightly overdressed in a fleece top and softshell trousers with thin waterproofs on top. It had started to lightly rain.
I eventually dropped into Coire an Lochain, even here the winds were gusting to above 40mph at 900m. The winds had steadily increased since this morning. On the walk back down to the Cas carpark the sun was shining over the Rothmurchis Forest and Strathspey. Meanwhile, behind me, the clouds were thick, dark and rain bearing.
