The Lanikai Pillbox Hike, also popularly known as the Kaiwa Ridge Trail, is one of the most picturesque and pleasant Oahu hiking trails. This intermediate hike rises just above beautiful Lanikai Beach, rewarding hikers with some of the best vistas of Oahu’s windward side.
Lanikai Pillbox Hike is ranked intermediate because of the steady steep grade of the uphill climb right from the start of the trail head.
The Lanikai Pillbox Hike is a moderate 1 hour to 90 minute hike (roundtrip), depending how far you decide to go. You can easily reach the first old military pillbox bunker in about 20 to 30 minutes.
