Beginning the steep ascent from the Pali Lookout, the Pali Puka trail climbs along the narrow ridgeline of the Ko’olau Mountains. High winds and sheer vertical drops make this short hike an exciting trip. At the trail’s peak is the Pali Puka, a “window” in the rock face of the mountain where King Kamehameha would watch for approaching enemies. The panoramic vistas provided by this exposed trail are incredible, offering breathtaking views of O’ahu’s windward coast, from Kailua all the way to Kualoa.
