Mokolii is a 12.5 acre, 206 foot tall basalt island one-third of a mile offshore of Kualoa Point, Oahu, in K?ne'ohe Bay, Hawaii, at . Geologically, it used to be connected to Oahu before erosion cut it off. It is also known as "Chinaman's Hat" for its likeness to the straw hats Chinese immigrants wore. Wedge-tailed Shearwaters are the only species of bird that nests here; previously there were a few.
Mokolii is open to the public from dawn to dusk. On weekends it is somewhat a popular secret with tourists and locals. It can be accessed by kayak, boat, surfboard, or by foot during low tides; depth soundings are only four feet on its west side.http://www.backyardoahu.com/index.html?moko1.htm This may be dangerous during any other time or inclement weather.
