I went a short way left along the lane, then took a footpath on the other side that continued through the delightful Chess Valley. The path initially ran between wooden fences, then followed the left edge of a small meadow of rough grass (by the Frogmore Meadows nature reserve). After passing through a small wood, the path continued between a wire fence and a hedge on my left. After several hundred yards I reached a path and track junction, with a footbridge over the Chess and the entrance to some water cress beds on my right. I just went straight on here, following a surfaced drive for several hundred yards until it ended at a bend in a lane.

I turned right along the lane. After a little while it went left, but I continued straight on along the valley bottom on a surfaced track or drive. When this eventually brought me to a gate, I turned right to cross a small footbridge over the river Chess at Sarratt Bottom (this being one of the most delightful spots I know in the Chilterns!).

The path crossed the floor of the valley and went through a gate. I then took a path forking right, which went uphill across a corn field, turning left on the far side between a fence and a hedge. In the field corner the path turned right, initially with a small wood to my left and then following a track to reach Mountwood Farm. I then just had to follow the straight and level drive from the farm for almost half a mile - it ended in the centre of Chenies, close to the green where I'd parked.

This was a nice day for a walk - the prolonged hot and dry spell had been briefly broken by heavy rain overnight, so there was a cooler and fresher feel to the day. As with last week's walk, I enjoyed this one more than I'd expected to - again it was on paths that I'd used many times before, but it seemed a while since I'd walked most of them and the route never felt over-familiar. In any case, the Chess Valley is so charming that I always enjoy walking here.
