Bluff Rock is situated 10km south of Tenterfield on the New England Highway. It was Edward Erby and his brother Leonard who passed the huge granite rock while moving to Deepwater Station from Tenterfield Station in 1842. They named the outcrop St. Swithins Bluff as they passed it on St. Swithins Day.
It is the place of the Bluff Rock Massacre. A monument on the site commemorates a massacre of Aboriginals. The Bluff Rock Massacre remains clouded by conflicting stories.
