In reply to sjc:
Park at the top of Buckhaw Brow. Go through the gate on the bridleway to Feizor and bear right at the top of the initial slope. The point you are aiming for is to the top left corner of the woods, there's a path (more of a wide worn strip of grass really) that drops down a little then gently rises. This path is on a levelish area *above* the scarp that is the continuation of Gigg South - you can see the last buttress of GS at the edge of the trees.
When you get above the woods, after about 200 metres you cut down to the right and contour beneath the crag. At no point do you cross any wall or fence to enter the woods.
Here's a shot
