Lanikai Pillbox Hike (Kaʻiwa Ridge Trail)
Kaʻiwa Ridge Trail
A short ridge trail between Kailua and Lanikai that climbs to WWII pillboxes overlooking Lanikai Beach and the twin Mokulua Islands, a prime sunrise spot.
The Lanikai Pillbox Hike, also known as the Kaʻiwa Ridge Trail, runs between Kailua and Lanikai. It is about 3 km round trip with about 150 meters of climbing. The first section is a steep dirt path, and in about 20–30 minutes you reach the first concrete pillbox from WWII, with a second one further on. From the summit you can overlook the blue-green water of Lanikai Beach and the Mokulua Islands (Na Mokulua) offshore, one of Oahu's most popular sunrise photography spots. The hike is free, with no facilities and almost no shade, so wear non-slip shoes and bring water. The trailhead is in a residential area, so do not park along the road. Park at Kailua Beach Park and walk over instead. It can be combined with a visit to Lanikai Beach.
