I did this circular walk of about 10.9 miles on Saturday, 29th July 2023. It was intended to be a repeat of the Shortened version of Ashridge Estate Boundary Trail that I've done several times before, but I ended up making it even shorter (due to fitness problems).
I couldn't park where I wanted to at the car park near Ringshall, as it was closed for resurfacing, so I turned down the drive to the Bridgewater Monument and parked at the car park just before the visitor centre and cafe (Grid Reference SP972131). I started walking about 8.45am, following the broad track past the visitor centre and cafe, with the monument over to my right. I soon entered the woods of Ashridge, as the track (a bridleway) started to descend towards Aldbury. After about a quarter of a mile, I came to a fork in the bridleway, where I kept left instead of going down to Aldbury. This bridleway now ran level through the woods for about half a mile - there was a nice view to the right at one point, looking out over Aldbury. On reaching a junction, I went a few yards right, then turned left, following a narrower bridleway through the trees (crossing a drive at one point) to reach a road (near Tom's Hill). I continued along the bridleway on the other side, keeping straight on for about another half mile (as usual following the waymarks for the Ashridge Estate Boundary Trail). I then came to a junction where the bridleway appeared to fork. I was sure I should fork right and then turn left after a very short distance, but a waymark for the Ashridge Estate Boundary Trail pointed straight on so I went that way. I soon came to another junction - here there was a waymark pointing left, which I knew was wrong, so I went straight on, soon leaving the woods and emerging on to the huge open grassland part of Northchurch Common, where I turned right. After a hundred yards or so I passed the point where I'd have come out if I'd followed the correct route.

Northchurch Common
I continued along the edge of the common. In a corner the path went straight on, back into the trees. I went straight on at a path crossroads (by another corner of the grassy part of the common). The path now ran through a more open area of bushes and occasional trees, soon with a valley dropping down to my left. I just had to follow the waymarks, taking a right fork at one point. This section always seems longer than I expect, but eventually the path then re-entered the trees and turned left, now following the southwest edge of Northchurch Common with fields just a few feet to my right. The path dropped down into a valley and rose a short distance up the other side before levelling out, still staying close to the fields on my right. It then dropped downhill into another small valley, where I turned left along a drive (coming from a property named "Goreseside's" on the OS map)
