Located in the centre of Cromwell, the College is situated on 8 hectares (20 acres) of park-like surroundings. There are extensive grassed areas and a courts complex for netball and tennis. College facilities include a 400-seat auditorium, a full-size modern gymnasium with mezzanine seating for 200 spectators, fully equipped weight room, and a well-stocked library.
