Lanikai Pillbox Trail (Kaʻiwa Ridge Trail)
Kailua / Waimanalo
Checking the forecast…
Kaʻiwa Ridge Trail climbs a narrow ridgeline above the Lanikai neighborhood in Kailua to two restored World War II observation stations (commonly called "pillboxes," though they were actually military observation bunkers rather than defensive pillboxes). The trail has become one of Oʻahu's most photographed hikes because of its incredible sunrise views over the Windward Coast.
Why Roamwise recommends this
Kaʻiwa Ridge Trail, better known as the Lanikai Pillbox Trail, delivers one of the highest effort-to-reward ratios on Oʻahu. In under an hour, hikers reach two historic WWII observation stations overlooking the turquoise waters of Kailua Bay, the Mokulua Islands, and the dramatic Koʻolau Mountains. While the climb is steep and exposed, its breathtaking sunrise views make it one of Hawaiʻi's most iconic hikes.
