Helen McLaren: Start at NJ333493 where you can park. Take track SW to a mast. At around NJ324490 you'll see an obvious track up through a ride - trust it as it takes you up to the low point between mast and summit where there's a track. Easy going and suitable for bikes.
Richard Webb: Don't go up from the south. There is probably a way, but I failed to find it in very heavy snow. I followed several promising tracks and gaps but met walls of snow-covered spruce every time. Tracks as shown on the OS map are iffy. Probably best by the forest road in from the west or east.
