KAILUA | Kaiwa Ridge (Lanikai Pillbox) Hike is a popular O’ahu hike. As you walk towards the summit, you’re rewarded with stunning views of the Mokolua Islands and Lanikai Beach to one side, and views of Kailua to the other. It’s an easy to moderate hike, 2.7km long with an altitude gain of 191m. The start however, is steep and slippery – it’s a good idea to use the safety ropes in this section.
The pillboxes themselves were built in 1943 by the US military during World War II. They were never equipped with defensive weapons, instead they operated as coast artillery observation stations.
There’s no public parking, and the hike, along with Lanikai beach, does get busy on weekends. A good time to visit is during the week, when things are a bit quieter, and there’s free parking in the residential neighbourhood at the end of Kaelepulu Drive, where the hike starts. The closest free public parking is at nearby Kailua Beach, about a 20 minute walk away.
