The rugged bush-clad slopes of Karioi rise to 2,480 ft on the west coast of the North Island and form the mighty southern headland of Raglan Harbour. This extinct volcano is dissected by deep ravines that radiate from the summit and terminate, on the western side, in towering coastal cliffs (Woody Head) that expose basaltic lava interbedded with volcanic fragmental material penetrated by andesitic dikes. The name Karioi means to loiter or idle.
