After the Garden of the Gods, Polihua Road becomes completely unpaved and is now simply called Polihua Trail. The bumpy path ultimately brings you to the beautiful 2-mile long white sand Polihua Beach on Lanai's distant north shore where frolicking humpback whales may be spotted in the wintertime. Past Polihua Beach on the lonely western tip of Lanai is Ka'ena Pt., where an infamous penal colony was once located in the 1800s for women who committed theft or adultery.
