The Pali Puka (Puka means “hole” in Hawaiian) hike is a great 1.5 mile round trip ridgeline hike that offers a maximum return on your time investment taking about 1-2 hours for the round trip depending on how much time you take to soak in and capture the beauty. Beginning from the Pali Lookout area, 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. The panoramic vistas provided by this exposed trail are incredible, offering breathtaking views of O’ahu’s windward coast, from Kailua and Kane’ohe all the way to Kualoa. At the trail’s peak is the Pali Puka, a small hole or “window” in the rock face of the mountain, said to be a hiding spot for Hawaiian warriors as they watched for approaching enemies.
