In East Honolulu at the Eastermost end of Maunalua Bay at the tip of Portlock is an area called China Walls.
Just around the point to the left of where the fisherman is standing in picture #6 is an area called Spitting Caves another popular spot used frequently for cliff diving.
Both areas are very dangerous and are not for the inexperienced even on apparently calm days.
The vista especially from China Wall is a sweeping panorama of Maunalua Bay and Diamond Head in the distance.
