Went with my 6 year old daughter. Parked the car on the A68 at the lay-by east of Byrness. Followed the forestry track to near Harry's Pike then left it for the cairn. Over a deer fence. This is the only difficult section... 2ft/60cm high tufts of grass and mounds of moss with intermittent bog land. Crossed another deer fence and then followed quad bike tracks to the summit. Weather was mostly cloudy but dry... we had one shower of snow/sleet/hail (in that order) that lasted 5-10 minutes. This gave way to a break in the clouds and some warm sunshine.
