Its formation was due to the Honolulu Volcanic Series, which were a series of eruptions by the Koʻolau Range that created numerous vents near Honolulu such as Diamond Head. Both Kāohikaipu and Mānana Island are northeast of Makapuʻu Point.

The islet is wildlife sanctuary for birds[3] and a permit is needed for people to access it.[4]
