I carried on along the path, passing close to the top of Boddington Hill on my left (there is a hill fort there, but I couldn't really see it). I went left at a junction where a path came in on my right, then turned right at the end of the track. I was now on the main track leading to the car park and visitor centre in Wendover Woods. After several hundred yards I turned right along a track or drive that passed through the 'Go Ape!' activity area (with people on high wires overhead). I continued past the car park on my left, and carried on along the exit drive until I came level with the visitor centre on my left (and a small blue traffic sign), where I took a path going right.

After a hundred yards or so, I turned left immediately after a bench, onto a surfaced path leading to some other activity area. But after another hundred yards or so, I took another path that started by passing between some railings on the right. This path is not shown on the OS map (it runs somewhere to the east of a path the map does show) but runs southwards through the easternmost part of Wendover Woods (initially the exit drive from the visitor centre was a little way to my left. I kept straight on at a number of path junctions, following the clear and level path through the woods for over half a mile.
View over The Hale to Barn Wood (where I'd be later on) - The Gruffalo seems to be enjoying the view!

Eventually I reached a junction where a path went left and I could see the path ahead starting to drop steeply. Here I took the path on the left, which after a while turned right (I must have been on the western edge of Hengrove Wood here) and brought me to a junction with another part of the Ridgeway (here rising uphill along another sunken lane). I crossed over and continued along a path on the other side, still in the woods but with fields close by on my left. After a few hundred yards this path joined the Ridgeway, where I continued more or les straight on and soon reached a lane (Hale Lane, which I'd been on earlier).
