Ko Tapu is a limestone rock about 20 meters (66 feet) tall with the diameter increasing from about four meters (13 feet) near the water level to about eight meters (26 feet) at the top. It lies approximately 40 meters (130 feet) to the west from the northern part of Khao Phing Kan island.

Ko Tapu formed during the Permian period and served as a barrier reef. During tectonic movements, the island ruptured and its parts were dispersed and flooded by the rising ocean. Wind, waves, water currents and tides gradually eroded the islands in some cases producing peculiar shapes, such as Ko Tapu. Tide-related erosion is visible at the bottom of the rock.
