Situated above Lanikai Beach on the Ka Iwi Ridge in Kailua, are the Lanikai Pillboxes which served as military observation points used to triangulate the positions of maritime vessels during WWII. A short hike to the top of the ridge and the two prominent pillboxes takes approximately 20-30 minutes. It is steep and often muddy, but the sweeping views of the Ko'olau Range and the twin Mokolua Islands is well worth the short scramble. The trail is frequently crowded, especially on weekends, but one great way to beat the traffic is to head up before sunrise with headlamps to watch the always spectacular sun rise over the Ka iwi Channel ('the channel of bones) between Molokai and Oahu.
