The parish of Sandon geographically contains the hamlet of Redhill (redirected here). However, the hamlet has spread out in recent times into the neighbouring parishes of Rushden and Wallington. The Post Office considers it to be in Rushden.
The eastern part of the Icknield Way Path passes through the village on its 110 mile journey from Ivinghoe Beacon in Buckinghamshire to Knettishall Heath in Suffolk. (From Ivinghoe Beacon westwards the path is known as The Ridgeway.)
