I like this walk because the terrain is at the more challenging end of the hill walking spectrum.
It includes steep ground and close views of the cliffs and corries of the northern Cairngorms. From a distance, because of their wide extent, the ‘Gorms can look rather rounded and tame. But this walk allows you to appreciate the scale of the great corries excavated from the plateau by retreating ice.
The ascent of the Fiacaill of Coire an Lochain can be an airy scramble. An easier alternative lies just to the west of the corrie rim. The descent of the Feith Buidhe to the shelter stone crosses treacherous slabs and braided streams that need care. At the head of Loch Avon, standing by the shelter stone, you are truly in the heart of the mountains.
In winter, the descent into and climb out of the Loch Avon basin should not be undertaken without a thorough assessment of the avalanche risk.
