Excellent walk, although a bit arduous in places. During the first climb up to the Ptarmigian restaurant, I followed a simpler route up the valley, from then on I followed the route description. Cairngorms was beautifully covered in ice crystals, visibility under 20 meters, certainly made the walk mysterious (and challenging). The section between Cairngorms and Ben Macdui was uneventful, apart from the breathtaking views. Ben Macdui itself easily accessible, with limited visibility and very strong winds.
The descent, following a ridge line, was quite heavy for my old knees, although it was very easy as a walk.
Warning
Please note that hillwalking when there is snow lying requires an ice-axe, crampons and the knowledge, experience and skill to use them correctly. Summer routes may not be viable or appropriate in winter. See winter information on our skills and safety pages for more information.
