White Coomb and Hart Fell from Grey Mare's Tail
Distance : 14km, ascent : 985m
The Grey Mare's Tail, a stunning waterfall 15km north-east of Moffat on the quiet A708, is the starting point for the approach up White Coomb and Hart Fell from the south. Leave a bike at Capplegill for the 6km return along the A708.
White Coomb
Start from the NTS car-park, which costs £2 to park at, and head up the well maintained path on the east side of the burn. As the path levels out above the waterfall, look for the dyke on the other side of the burn. Cross the burn, which should prove easy enough, then follow the wet path on the north side of the wall uphill. The path reaches White Coomb's summit plateau, leaves the wall and aims directly for the cairn.
Hart Fell
Leave the cairn, aim west-north-west, cross the fence-line, then follow the fence-line on its south-side to Firthhope Rig. A faint path forms on the way and this is followed downhill (ignore the fence-line heading off left further down, cross the gate instead) to Rotten Bottom - a sodden bealach. Briefly uphill, then more fence following to the base of Hartfell Rig and 1km further on, the summit trig point on Hart Fell is reached.
Return
To return, head east and start to drop downhill - it's not as steep as the maps would suggest ! Progress is easy over grass covered ground as Cold Grain burn is picked up to follow down to the track that travels out of Black Hope back to the A708 near Capplegill.
