Scrabo Country Park, in which the tower stands, includes parts of the top and the eastern and southern slopes of Scrabo Hill as well as Killynether Wood. The eastern part of the hill is of geological interest because outcrops in the South Quarry reveal contacts between sediments (sandstone) and locally cross-cutting sills of intrusive rocks (dolerite). This eastern part, which includes the site of the tower, has been declared an Area of Special Scientific Interest (ASSI). Much of the plateau on top of the hill to the west of the tower is occupied by Scrabo Golf Course.
