In reply to nedhed:
Apart from a slight frost today its been the usual warm and wet, so yes a bog trot from the usual approaches. FWIW I only go up cheviot when its under snow and been well below freezing for several days, that way I can walk over the top of the bog and I'm local! If you want the drier approach then you'l need to go from the North, its a more asthetic route anyway. Park at Heathpool, bike the 5km up the private tarmac road to Mt Hooley bunckhouse, leave bike. Follow track up into the "Henhole" past the crags and out steeply on the right to emerge at Auchope Cairn, follow flaged path to summit, you can return down path to near the rescue shelter and freewheel back down the road!
