I followed the path eastwards for about half a mile, as it ran between hedges or fences either side, with a couple of pastures on my right. On finally coming to a path T-junction I turned right, this path running between old hedges either side for a hundred yards or so. On reaching another path T-junction I went left, and soon reached Narcot Lane. A path continued on the other side, running between a tall wire fence and hedges or trees on my right. It curved left to head northwards towards Chalfont St Giles. After almost half a mile it passed an old orchard on my left, and a few hundred yards further on it met a crossing track by a house on my right.

I went straight on, following the right edge of what I presume is a park, going up and down a dip and then passing a bowling green on my left (hidden behind a hedge). The path continued on past some sports fields on my right (there was a surprising number of spectators watching a soccer match on one of them). On coming to a corner, the now surfaced path went right and then immediately left (to continue in the same northwards direction as before), and then ran gently downhill between hedges and fences to reach a road in Chalfont St Giles. I turned right, soon passing Milton's Cottage (a 16th century building where the poet John Milton once lived, now a museum) on my right. The road curved slightly left to reach the centre of the village, where I turned left along Stratton Chase Drive (the Chiltern Way and South Bucks Way both go along here). After a while the drive curved left, but the public footpath carried straight on, following the Misbourne valley and soon reaching a bend in Mill Lane.
