26B Torlum
Park at the end of the forest road at Balloch Cottage and walk W to the junction. Although it looks obvious to head NW up the slope of felled trees from here (which is the way I went), instead turn left and follow the road to another junction at NN824186 where you turn R. Follow the track WNW then NW to get to a good track at NN820188 which goes to the summit trig point.
