Across the lane the path ran across a grassy area next to the farm. It then followed the edge of a field (right) to reach a corner of Stonehill Wood. The path continued through this wood, going from the southwest corner to the northeast corner (I went straight on where paths went left and right). I then turned right along a bridleway, which ran for some distance just inside a wood called Ashen Grove, with fields on my right. The bridleway then ran a short way between hedgerows before joining the drive from Dundridge Manor.

At the end of the drive, I went a few yards right then took a path on the other side of the road. This crossed part of an empty paddock or pasture (going half-right), then went across a corner of a paddock, before continuing diagonally across another paddock. It then went half-right, along the bottom of some gardens in Buckland Common on my left. The path continued along the bottom of a shallow valley, passing two large ploughed fields on my right. Further on it passed through three pastures, still following the valley bottom. I then turned left and followed a road (Rays Hill) quite steeply up hill to reach Hawridge Common, where I turned left to return to my car.

This was another pleasant walk. I hadn't walked this particular route for some years, but many of the paths were ones I've walked often since then - the section from Chesham along Herberts Hole and on to Bellows Wood was the only part with which I wasn't too familiar. Unfortunately it was another fairly grey day, only brightening up towards the end, but then that's fair enough for late October.
