I did this circular walk of about 13.3 miles on Friday, 23rd August 2019. It was another repeat of a walk I first did in September 2011 - I've also walked the route in the opposite (clockwise) direction a couple of times, most recently in October 2016. (Note: sorry, the descriptions here are very much a 'cut and paste' from the last time I did this walk).
I couldn't find a place to park in the centre of Chenies where I usually do, close to the old pump on the green (Grid Reference TQ 016984), so instead I parked a little further along the road from Chesham, somewhere between the two pubs, and started walking about 10:05am. From the village green I took the road to Chesham, but left it as soon as it left the village by taking a track called Holloway Lane on the right. After a few hundred yards, just after the 'lane' turned left, I took a path that forked half-right and dropped downhill across a grassy field. In the valley bottom I rejoined Holloway Lane (which had turned right), and followed it to the right for about a quarter of a mile. When it turned left I went straight on along a footpath through Mount Wood for about half a mile, until I emerged from the other end of the wood at Sarratt Bottom.

I continued straight ahead, following the path past the overgrown area at Sarratt Bottom and then on through a long thin pasture to reach North Lane. Here I turned left and soon crossed the river Chess at Sarrattmill Bridge. After another 100 yards or so I turned left along a footpath that followed a surfaced drive. As I reached a cottage on the right, I turned right and followed a path that went steeply up a grassy hillside, alongside a fence on my left. At the top of the slope I crossed a drive and continued straight on a short way to reach the end of a lane at Church End, a hamlet within the parish of Sarratt.

I walked through the churchyard, and stopped for a few minutes to take a look inside the church where I aw a Mediaeval wall painting. I then crossed a small meadow or pasture to a metal kissing-gate and then continued across a large empty pasture, where after a while there was a nice view towards the Chess Valley over to my left. I spotted a gentleman here that I'd seen coming the other way through Mount Wood. He was carrying a small basket and obviously looking for mushrooms, and I was able to point some out to him that were on the path. The path eventually followed a row of trees on my right to reach a gate in the field corner.
