The Pangbourne to Goring section of the Thanes Path is the only stretch where you have to go up or down a hill. This, of course, is due to the missing ferry at Gatehampton.
The path from the top of Whitchurch Hill through Hartslock Wood has a sudden feel of being on a cliff.
Now there are complaints about the steep descent near the start of the path where there used to be steps. In the Henley Standard two walkers who met at the bottom of the slope compare notes.
