On the second day of a 1:1 Wet and High Adventures Winter Skills course, we headed up onto the plateau for some winter navigation. Ascent via Fiacaill a Choire Chais to 1141 and up onto Cairngorm gave us some challenging conditions. Bitterly cold and biting winds meant it was a goggles day with frequent visibility issues. This was good for navigation practice. The plateau is scoured and the Cairngorm weather station frozen solid, hence no wind readings on the website.
