Nu‘uanu Pali State Wayside, 7 mi. n.e. via Pali Hwy. (Hwy. 61), offers a dramatic panorama of windward O‘ahu’s valleys and coastline. This windy 1,200-foot-high gap, flanked by cliffs that rise 2,000 to 3,000 feet, was the scene of Kamehameha the Great’s decisive victory in the conquest of O‘ahu in 1795. Winds are usually so intense that visitors can lean against a “wall” created by the current.
