Olomana is a set of three mountainous peaks on the windward side of Oahu near Kailua and Waimanalo. While historically only the first peak was called Olomana and the second and third Paku'i and Ahiki respectively, most people call the entire section Olomana. Geologically speaking, Olomana is an erosional remnant from within the caldera of the Koʻolau Volcano.
