The path starts from this gate (which you do not need to pass through) alongside the footpath from Souldern Grounds.
The path just consists of following this field boundary down the hill to the canal.
The bridge may be up to allow boats through.
You can raise the arms to lower the bridge to walk across. (If you are approaching the bridge from the other side and it is up, there is a rope that you can pull).
The Canal towpath looking north towards Wharf Farm and Aynho.
