Immediately after going through a third gate, I turned left to follow a path up to the top of Watlington Hill. This ran a short way through a wood, including a section of Yew trees. It then ran beside the Yew wood on my right. The path had so far been gaining height gently, but shortly after the Yew Wood ended I turned slightly right on to a fainter path that climbed more steeply. At the top of the hill I stopped to take some photos.

I then continued along the top of the hill, sometimes with views to Shirburn Hill and Pyrton Hill on my left. The path went though a gate, and it was then surfaced as it led on to a small bit of wood and then the Watlington Hill car park.

From the car park entrance I turned right along the road, following it for a straight quarter of a mile to a T-junction on the edge of Christmas Common. I turned left, and just after leaving the village turned right onto a footpath that started down a drive. When the drive turned right, I continued on into Shotridge Wood, the path soon curving left. On reaching a junction I went right, the path curving right and passing some small pits on my right. I soon came to another path junction, where I turned left onto a long path that descends gradually through the woods to eventually reach the Wormsley Valley, though I wasn't following it that far today.
