Reach the col at 489 metres and descend the Allt Gartain trail to a path junction just north of the road at NN 172516 (3.8 miles/6.1km). Turn R and follow the valley north along the Lairig Eilde trail, bearing R down the Allt Lairig trail. Trend R back to the A82 by a cairn and layby at NN 187562 (7.1 miles/11.4km).
