Beyond this field I crossed the drive to Studdridge Farm and carried on along a path that followed the right edge of a meadow. On then entering Commonhill Wood, the path turned slightly left and descended very slightly to cross the beginning of a valley (it kept right at an apparent fork here). The path continued through the wood until it reached the minor road that runs from Stokenchurch to Ibstone (to my left).

I went a very short way right along the road, then took a bridleway on the other side. Fairly soon this turned left and then gradually descended through Bowley's Wood for several hundred yards, before the bridleway turned right and continued down through the wood to reach the valley bottom near Woodend Farm on the Wormsley Estate.
