Cairn Toul is the 4th-highest mountain in Scotland and all of the British Isles, after Ben Nevis, Ben Macdui and Braeriach. The summit is 1,291 metres above sea level. It is in the western massif of the Cairngorms, linked by a bealach at about 1125 m to Braeriach. The mountain towers above the Lairig Ghru pass. Cairn Toul is often climbed together with other peaks. From the south, it may be climbed with The Devil's Point, which lies about 2.5 kilometres south-southeast.
