The path continued up the other side of the valley, still in East Wood. After a few hundred yards it turned right, and descended into a small valley, As it started up the other side, I looked carefully for an arrow on a tree showing where the public footpath forks slightly right from what was now a clear track (I managed to go wrong here once) - the first few yards of this bit of the path were somewhat unclear, but then I found another arrow on a tree and the path became much clearer. I eventually spotted a finger-post pointing towards me, but had to skirt some brambles to get to the drive the post was positioned by, where I turned right and within a few yards reached a B-road just south of Stokenchurch. I turned left along this road, immediately crossing the M40 motorway.

I then turned right onto another footpath, that dropped down a small embankment and continued between hedges with what are now sheep pastures either side. Through a couple of gates, close to Penley Farm over to my left, the path continued along the right edge of another sheep pasture, as far as a finger- post that indicated where it turned left and crossed the pasture. On leaving this field, the path turned right and headed downhill through Penley Wood. By Chiltern standards this was a long and steep descent (which probably explains why I've walked this path in this direction many times, but only once in the opposite direction!). I spotted some Fallow Deer as I neared the bottom of the valley, where I turned left along a bridleway (I think the valley is called Twigside Bottom, at least that's the name on the OS Map about a mile south from here).
