Located just west of Little House, Big House was named after a large house onshore, once used by captains for navigation before mooring balls were installed.
Like many Half Moon Bay sites, Big House is an underwater playground of rocky canyons, ridges, tunnels, and archways. But it also features deeper sandy areas and tall ridges extending into the blue. Some ridges have sand buildup on only one side due to prevailing currents—a fascinating natural phenomenon.

Often, a Bar Jack shadows them, turning from silver to black while following—an intriguing colour change behaviour unique to this species!
