The Cairngorms 4000s links five of Britain’s highest summits across a remote, exposed plateau and the Lairig Ghru. Even when the general pattern is settled, cloud, wind and temperature can differ across this large mountain area.
Use the challenge grade to compare dates, then inspect all five rows. The forecast does not account for river crossings, snow cover, navigation or the very substantial distance between summits.
