Aiea Loop Trail
A 4.8-mile loop trail through a forest of eucalyptus, Norfolk pines, and native plants with views of Pearl Harbor and the south shore. The trail is mostly shaded which makes it one of the more comfortable hikes on Oahu even on warm days. Kids enjoy the variety of terrain and the WWII airplane wreckage along the trail adds historical interest. The loop format means no backtracking. The trailhead is inside Keaiwa Heiau State Recreation Area which has picnic areas and a campground for extending the visit.
