Nanahoa islets are a collection of 4 sea stacks off the western coast of Lanai, located just offshore near Honopu Bay. The islet closest to the main island of Lanai is the tallest and has the most vegetation on it, though vegetation was only observed on the top surface. This islet is shaped like a round pillar of rock with a slanted top and stands about 128 ft. high. 

Just past this pillar are two medium sized rocks, one similar in shape to the large islet, but smaller in stature that also has some vegetation on the top surfaces, and one with a more pointed top with vegetation mostly near the top on the side. The furthest rock out is the shortest and is somewhat shark fin shaped.
