On leaving Hoo Wood, the bridleway then ran between a fence and some garden fences, with a huge pasture sloping down to my left (I spotted a few more Fallow Deer here). Through a gate I turned right, now on a byway according to the OS map, and went about another hundred yards towards a gate, beyond which was the road through Little Gaddesden. Instead of going through the gate to the road, I turned very sharply left, and took a path across a paddock. The path continued across a pasture containing some sheep and one or two large white cows. After a while the path had a fence on my right. Beyond this pasture the path crossed a paddock to reach Little Gaddesden church.

I continued along a drive past the church, on my left, and when the drive turned left beyond the churchyard I went straight on along a path across a meadow - once again the nice view, looking back left towards the start of what becomes the Gade valley with a bit of the Vale of Aylesbury beyond, was nowhere near its best. The path then ran for several hundred yards beside an arable field, following a hedgerow on my left. At a path junction, close to a solitary tree in the corner of the field, I went straight on, along the left edge of a paddock to reach a private road in Hudnall. I turned right and followed it to reach a crossroads, where I went straight on along St Margarets Lane (or at least that's what the far end of it is called). After a while this turned slightly left, and then I had a large grassy part of Hudnall Common on my left.
