Sarn Ford is the stone ford on the River Baranduin, on the far southern borders of the Shire. It was guarded by the Rangers of the North.
A road beginning at Michel Delving crosses the ford, which meets the Greenway further south. By this road Khamûl the Ringwraith entered the Shire during the War of the Ring
The name is half-translation of the Elvish name Sarn-athrad. Sarn means "stone".
- "Hall Green village was only a little distance away [from Sarehole] down a lane and across a ford."
