Pete's Walks - Coombe Hill and Kingsash (with HS2 diversion) (page 1 of 6)
If you are considering walking this route yourself, please see my disclaimer. You may also like to see these notes about the maps and GPX files.
I did this circular walk of about 11.9 miles on Friday, 23rd June, 2023. It was meant to be a repeat of a walk I've done a few times before, most recently in October 2018, but it was lengthened by about two thirds of a mile because of a path diversion caused by construction work for the HS2 railway (Boo! Hiss!).
I parked at the Coombe Hill car park (Grid Reference SP 852063), and started walking about 9.20am. From the gate by the car park entrance, I took the middle path that crossed the centre of a flat area of grass and bushes. After going through a belt of trees, I turned right and followed a broad band of grass towards the Boer War monument on top of Coombe Hill. On reaching the monument, I admired the view out over the Vale of Aylesbury and then turned right to follow the Ridgeway national trail (white acorn signs) towards Bacombe Hill

After a few hundred yards I had to go through gates either side of a bridleway in a sunken lane or 'hollow way', my path then running between bushes or small trees for some distance. At a junction (by an information board) where the Ridgeway forked left, I went straight on, soon going through a gate and almost immediately forking right at a vague fork in the path. I carried on along the top of Bacombe Hill, where I saw several wildflowers including Common Spotted Orchid, Herb Robert and the tiny Squinancywort. I kept right where the path seemed to split in two and after a few hundred yards I reached a tumulus or burial mound (the hill drops more steeply after this) where I turned right (another path goes right just before the tumulus, the two paths joining up just after entering some trees).

The path dropped downhill to reach a bridleway. Across this I went over a stile and followed a path that went slightly left as it descended through a grassy field (there were a few young bullocks here). I then turned left and followed Bacombe Lane for about half a mile, passing some works for the HS2 railway at one point, to reach the edge of Wendover. Here I turned right along a road for a few yards, before going down Chapel Lane on the other side. I followed it to where it crossed a stream, when I turned right along a path with the stream on my left. I soon came to a path junction, where I turned left, crossing a footbridge over the stream and continuing a short distance between garden boundaries.
