Kāohikaipu (also known as Black Rock) [1] is an islet located in Honolulu County, Hawaii, off the east coast of Oahu. It is situated 0.6 miles (0.52 nmi; 0.97 km) from nearby Mānana Island (Rabbit Island). [2] [3] Both Kāohikaipu and Mānana Island are northeast of Makapuʻu Point. The total size of Kāohikaipu is 11 acres (4.5 ha). [3] [4]
Kāohikaipu′s 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.
The islet is a wildlife sanctuary for birds [3] and a permit is needed for people to access it. [4]
