Near the gate to Hallbottom Farm, I went over a stile on the left and followed a path between fences with empty paddocks either side. The path continued slightly uphill through a corn field, then followed a hedgerow along the edge of another corn field. The path then entered Lott Wood, descending gently close to an edge of the wood to my right. On reaching a valley bottom, I turned left along a bridleway which ran along a track between Lott Wood and Crowell Wood (on my right). Further on, the wood on the right became High Wood. Also somewhere along here I spotted a pair of butterflies that again might have been Silver-washed Fritillaries, but again they didn't settle and I couldn't be sure.

Further along the same track - the wood on the right is probably now High Wood
After several hundred yards I came to a path junction - the bridleway actually went left here, but I continued ahead along the track, which was now a public footpath. The track now curved right and continued through what was now Kingston Wood (I think, the boundaries of all these woods aren't too clear on the OS map). When the track ended, the footpath carried on through the wood, soon entering Crowellhill Wood. Eventually it reached the lane through the hamlet of Crowell Hill, where I turned right.
The track after it curves right, just after a path junction - this is now a footpath, up to the junction it was a bridleway (according to the OS map)
Fro the end of the track, the path continues through Kington Wood ...
... somewhere along here I went from Kington Wood to Crowellhill Wood
Crowellhill Wood
It started to rain as I walked down the lane, and I had to stop to put my rain-jacket back on (I'd taken it off earlier when I'd started to get a bit too warm). I followed the lane as far as the entrance to Crowell Hill Farm (on my right), where I turned right onto a bridleway. This ran as a muddy sunken lane, descending through a wood. Near the bottom of the slope there was a bridleway fork, where I kept left, the bridleway then running along the bottom of the valley, After a few hundred yards it emerged into the open, though Crowell Wood remained on my right. A line of trees had been felled on my left, I'm fairly sure they were standing the last time I came this way. Further on the path entered the wood, but stayed fairly close to its edge on my left.
