After a short distance the track passed the kennels on Clipper Down. It continued through the woods of Ashridge, largely following a steep slope going downhill on my right, with occasional views out in that direction. Much further on there was an area where again there was a lot of Ramsons or Wild Garlic, and a little further on I passed another ancient burial mound, Moneybury Hill Barrow. Eventually, after following the track for about a mile and a half, I reached the Bridgewater Monument.

Approaching the Bridgewater Monument at Ashridge
I crossed the grass in front of the monument, and on the far side (just right of the visitor centre and cafe) turned right on a track. This headed gently downhill through more of the Ashridge woods. After about a quarter of a mile I reached a bridleway fork where I kept left (the other fork goes down to Aldbury). This bridleway was now fairly level and well-surfaced, and after a while there was a bench where there was a nice view out to my right, over Aldbury and its surroundings. When I reached a path junction, I turned sharply right for a few yards, then turned left to resume the same direction as before. This bridleway crossed a drive and soon reached a minor road (near Tom's Hill).

View right, looking out over Aldbury - this was the third point I'd come to where a seat had been positioned to take advantage of a view out through a gap in the trees

Across the road, the bridleway continued for about half a mile through more of the Ashridge woodland. I just kept straight on at various junctions, but paid heed to the Ashridge Estate Boundary Trail waymarks. Eventually I came to a fork where the waymarks indicated I kept right, then a few yards further on they showed I had to go left at a second fork. I then soon emerged on the edge of the huge grassy part of Northchurch Common. Here I turned right, following the edge of the grassy area to a corner where the path went straight on through a corner of trees. The path then continued through a slightly more open area of trees and bushes, with a small valley developing on my left.
