After following the track along the valley bottom for about half a mile, I took a footpath on the left (again waymarked), going straight uphill along a clear grassy track between the trees. There was a wire fence on the right. It was further up here than I remembered before I reached a white arrow on one of the fence posts indicating where the path left the track and went half-right (still following the fence, initially). Further on the path bore slightly left, away from the fence and through a patch of tall bracken. It then crossed a track and continued northwards through the wood. Eventually it dropped down into a slight valley and then briefly rose steeply up the other side, before finally leaving the wood.

The path then continued beside a tall hedge on the right, past one ploughed field and into another. When the hedge turned right, the path went half-right across a corner of the field (I actually just followed the hedge), then went past a garden (of a house named Arbor on the OS map) on the left to reach a lane. Across this, a path crossed a stubble field, bearing slightly right. There were some nice views here - to my right, I could see a long way across the Thames Valley towards Berkshire, while ahead and slightly left I could see part of my route that I would soon reach, approaching Frieth Road.

On the far side of the stubble field I reached another lane, where I turned left and followed the lane gradually downhill. At the bottom of the slope I turned right onto a footpath which would take me to Frieth Road - this had changed since I was last here, as it was now enclosed by fences. It went a little way straight uphill then turned half-right to reach the top of the slope. Over the rickety remains of a stile, the path then ran for several hundred yards between a wire fence and a tall hedgerow on my right. Beyond a kissing-gate, the path then turned left to go uphill (less steeply than I remembered - most unusual!) through a large empty pasture (there have been cows or sheep here on other times I've walked this path), following the hedge on my left. At the top of the hill I reached Frieth Road (that's just the name of the road, it's in the parish of Great Marlow).

I turned left along Frieth Road. After about a quarter of a mile I turned right along a bridleway that followed the drive to Munday Dean Farm, which went steeply downhill (I'd forgotten quite how steep this was). At the bottom of the slope I went left, along Munday Dean Lane. At its end I continued ahead along a short byway between hedges. When this ended at a junction with a bridleway, I turned left for a few yards, only to turn right onto a footpath as soon as the bridleway entered Shillingridge Wood.
