I entered the car park, then turned sharply right onto a bridleway that started up a short flight of 'steps'. The bridleway ran through a wood, parallel to the road nearby on my right, until it met a track, where it went a few yards right to reach a gate by the road. Here the bridleway went left, while a public footpath went more sharply left. The bridleway now curved left in a semi-circle, until it met the footpath coming in from the left (this is not really shown at all on the OS map), I now turned right, still on a bridleway, and continued through what was now Pond Wood. After a while the wood changed into a typical beech wood, and then the bridleway continued through a narrow tree belt (still mainly beeches) with a misty view towards Chequers, the Prime Minister's country residence, to my left.

Across the road a footpath crossed a large arable field (there were some white and yellow plastic stakes marking the route) to reach a lane, where I turned left to follow a lane through the hamlet of Bigmoorend. At its end I turned right onto a section of the Ridgeway, which was soon climbing quite steeply up through Goodmerhill Wood. At the top of the slope the Ridgeway turned left, and I carefully continued to follow its fingerposts and white acorn signs through the wood. At one point it joined a broad track, possibly now in Linton's Wood. Further on this passed through a gap in a wooden railing, and a little further on reached a road on Lodge Hill, where I turned right.
