The Aiea Loop Trail is 4.8-mile long trail with an elevation gain of 900 feet and a trailhead in a park near the campground. The trail runs most of the way along the ridge above the Halawa Valley and is surrounded by groves of fragrant lemon eucalyptus trees, Norfolk pines, and native ohi’a and koa trees. It is full of steep switchbacks, and you will have to jump over a stream and a few tree roots, but you will love the view of Oahu’s southern coastline from Pearl Harbor and the Wai‘anae Range to Diamond Head and Honolulu. The trail is considered moderately strenuous and can be done in less than three hours.
