Christmas Point is unique in character due to the condition of many of its rock formations: concave rather than convex. It seems as if a giant ice cream scooper has carved out portions of the rocks to leave them with these unusual shapes. Apparently the area must have been above the water millions of years ago and was subject to shaping by oncoming waves.

A number of underwater caves contain overhead air pockets which were filled by exhaling scuba divers and now serve as fascinating horizontal mirrors.
